## Abstract

This study is associated to solve the nonlinear SIR dengue fever system using a computational methodology by operating the neural networks based on the designed Morlet wavelet (MWNNs), global scheme as genetic algorithm (GA), and rapid local search scheme as interior-point algorithm (IPA), i.e., GA-IPA. The optimization of fitness function based on MWNNs is performed for solving the nonlinear SIR dengue fever system. This MWNNs-based fitness function is accessible using the differential system and initial conditions of the nonlinear SIR dengue fever system. The designed procedures based on the MWNN-GA-IPA are applied to solve the nonlinear SIR dengue fever system to check the exactness, precision, constancy, and efficiency. The achieved numerical form of the nonlinear SIR dengue fever system via MWNN-GA-IPA was compared with the Runge–Kutta numerical results that verify the significance of MWNN-GA-IPA. Moreover, statistical reflections through different measures for the nonlinear SIR dengue fever system endorse the precision and convergence of the computational MWNN-GA-IPA.

## 1. Introduction

Dengue fever disease (DFD) is one of the epidemics, infectious, and serious diseases that disturbed about 2.5 billion individuals all over the world. DFD occurred in some main countries of Southeast Asia due to the hot seasons. The infectious DFD grows fast, when the environment alters and becomes dangerous because of the shortage of information amongst the individuals [1]. DFD is an epidemiologic transmittable fever formed by dengue infection (DI) that is conveyed through mosquitoes to humans and apes [2]. Some symptoms scientifically produced by DFD are headache, joint pain, skin rash, and DI. The global World Health Organization (WHO) classified DI into a hemorrhagic dengue fever before one decade [3]. DI is categorized into three organizational proteins, membrane protein (M), envelope protein (E), and capsid protein (C), while it has seven proteins that are nonstructural and their names are NS-I, NS-IIA, NS-III, NS-IIB, NS-IVA, NS-IVB, and NS-V [4]. According to envelope protein antigenicity, DI is ordered into four classes of microorganisms, which are infected as well as pathogenic [5].DI has been reported in several zones of China and still any scientific report cannot prove it a confined endemic [6], whereas all other subgroups of DI have been imported; DI-I and DI-II are considered in China one of the main stereotypes endemic. In the Chinese province Guangdong, DV-I reported around 70% in 2014 and 80% in 2015. Presently, an amino-based acid localizes transformation in NS-I of the Asian “Zika” inheritance, which has been described to grow the production of NS-I in the diseased host to make the virus convenient to Aedes type of mosquitoes, which is the focal wide spreading cause of virus “Zika” since 2015 [7].Some epidemic infections such as COVID-19 are the existing transferred diseases, which have covered the whole world and the infection rate along with the number of deaths from COVID-19 increased steadily [8]. Another common disease is malaria, which is not directly transmitted from host to host. Protozoa is one of the transferred diseases, which spreads due to the anopheles of the female mosquito. According to the WHO report, almost 1/3 million individuals per year die from malaria. It distresses the children and pregnant women, mostly in the South African and American countries. Many chemical sprays have been widely implemented to control the mosquito population. Similarly, nonpolluting types of biological arrangements normally accomplished to emphasis the ecosystem of complicated kinds. The sterile insect apparatus (SIA) is a proficient nonpolluting scheme of insect control, which depends on the sterile male’s release. Consequently, adequately sterile males discharging causes the elimination of the wild’s population. Over a half century ago, SIA has been recognized in the Curacao Island to adjust the screwworm hover [9, 10].The aim of this study is to solve the nonlinear SIR dengue fever system using a computational methodology by operating the MWNNs, global search GA, and rapid local search IPA, i.e., MWNN-GA-IPA. The stochastic approaches have been investigated normally to solve a number of applications directed to the differential linear/nonlinear systems [11, 12]. However, no one has applied the MWNNs to solve the nonlinear SIR dengue fever system. Few recent reported submissions of stochastic solvers are eye surgery model, functional singular system, Thomas–Fermi singular equation, HIV-based infection system, biological form of the prey-predator system, periodic singular problems, singular three-point differential model, COVID-19 SITR system, multifractional singular models, system of heat transmission in human head, and mosquito spreading in heterogeneous conditions [13–15]. The intention of this study is to solve the nonlinear SIR dengue fever system using the MWNN-GA-IPA. The literature form of nonlinear SIR dengue fever system is written as [16](1)dXτdτ=μh−μhXτ−αXτZτ,X0=I1,dYtdτ=αXτZτ−βYτ,Y0=I2,dZtdτ=γYτ−γYτZτ−δ1Zτ,Z0=I3,where the susceptible class, infected class, and recovered class are Xτ, Yτ, and Zτ, respectively. The terms γ,μh,δ1,α, and β used in system (1) are constant, whereas the initial conditions are I1, I2, and I3, respectively. Few major geographies of the MWNN-GA-IPA are concisely given as follows:(i)
Design of Morlet wavelet is presented successfully as an activation function to solve the nonlinear SIR dengue fever system(ii)
The reliable, consistent, and stable overlapped results obtained by the MWNN-GA-IPA and the true solutions validate the exactness of the proposed approach(iii)
The authentication of the presentation is trained via different statistical valuations to get the solutions of the nonlinear SIR dengue fever system on multiple executions of the MWNN-GA-IPAThe rest of this paper is reported as follows: Section2 indicates the proposed MWNN-GA-IPA along with the statistical measures. Section 3 shows the results simulations. Section 4 describes the final remarks and future research reports.

The mathematical form of MW function is written as [18](4)Hτ=cos1.75e−0.5τ2.The simplified form of system (2) using the above MW function is given as(5)X^τ,Y^τ,Z^τ=∑i=1mvX,icos1.75wX,iτ+uX,ie−0.5wX,iτ+uX,i2,∑i=1mvY,icos1.75wY,iτ+uY,ie−0.5wY,iτ+uY,i2,∑i=1mvZ,icos1.75wZ,iτ+uZ,ie−0.5wZ,iτ+uZ,i2,,X^nτ,Y^nτ,Z^nτ=ddτ∑i=1mvX,icos1.75wX,iτ+uX,ie−0.5wX,iτ+uX,i2,∑i=1mvY,icos1.75wY,iτ+uY,ie−0.5wY,iτ+uY,i2,∑i=1mvZ,icos1.75wZ,iτ+uZ,ie−0.5wZ,iτ+uZ,i2..An error function based on the merit function is given as(6)e=∑j=i4ej,(7)e1=1N∑i=1NX′^i−μh+μhX^i+αX^iZ^i2,(8)e2=1N∑i=1NY^′i−αX^iZ^i+βY^i2,(9)e3=1N∑i=1NZ^′i−γY^i+γZ^iY^i+δ1Z^i2,(10)e4=13X^0−I12+Y^0−I22+Z^0−I32,where X^i=Xτi,Y^i=Y^τi,Z^i=Zτi,Nh=1, and τi=ih. X^i, Y^i and Z^i show the proposed results of the susceptible class, infected class, and recovered class. Likewise, e1,e2, and e3 denote the error function related to system (1), whereas e4 denotes the error function on the basis of initial conditions.


### 2.2. Optimization: MWNN-GA-IPA

The optimization performance is presented for solving the nonlinear SIR dengue fever system using the MWNN-GA-IPA. The structure of the present approach to solve the nonlinear SIR dengue fever system is provided in Figure1.Figure 1
Structure of the present approach to solve the nonlinear SIR dengue fever system.GA is a global optimization procedure, which is executed to solve the nonlinear SIR dengue fever system by implementing the usual selection procedures. GA is pragmatic frequently to regulate the accurate population to solve several complicated or stiff systems. To attain the best model outcomes, GAs operate through the operators based on selection, reproduction, crossover, and mutation. Few existing GA’s applications are the hospitalization expenditure system [19], feature assortment in cancer microarray [20], organization of irregular magnetic character brain tumor imageries [21], vehicle routing system [22], prediction-based traffic flow system [23], radiation shielding optimizations in the bismuth-borate spectacles [24], prediction of air blast [25], composition optimization of cloud service [26], task arrangement models in phased range radar [27], arrangement system of microarray cancer [28], system dynamics of monorail vehicle [17], and prediction system of liver disease [29].IPA is known as an optimized local search approach, which is performed broadly in both types of models (constrained/unconstrained). IPA is used in the optimization of various complicated and nonstiff natured systems. Recently, IPA is executed for image restoration [30], multistage nonlinear nonconvex models [31], viscoplastic fluid flows [32], nonsmooth contact dynamics [33], power systems [34], and dynamic flux balance analysis models [35]. The hybridization process of GA-IPA is applied to remove the laziness of GA, i.e., global approach. The pseudocode based on the designed approach MWNN-GA-IPA is provided in Table 1.Table 1

Figure 2 shows the set of best weights and comparison of the best obtained results with the Runge–Kutta numerical results. It is seen that the proposed and reference results overlapped each other for X^τ,Y^τ, and Z^τ classes to solve the nonlinear SIR dengue fever system. The plots of the AE for X^τ,Y^τ, and Z^τ classes to solve the nonlinear SIR dengue fever system are reported in Figure 3. For the X^τ class, Y^τ class, and Z^τ class, the AE best values lie about 10−6–10−8, 10−3–10−5, and 10−4–10−6, and the AE mean values lie around 10−1-10−2, 10−2-10−3, and 10−3-10−4, respectively. The performance plots of the E-VAF and T.I.C indices for each class of the nonlinear SIR dengue fever system are plotted in Figure 4. For X^τ category, the best E-VAF, M.A.D, and T.I.C values lie around 10−6–10−8, 10−5-10−6, and 10−9-10−10. For Y^τ category, the best E-VAF, M.A.D, and T.I.C values lie around 10−5-10−6, 10−3-10−4, and 10−8-10−9. Similarly, for Z^τ class, the best E-VAF, M.A.D, and T.I.C values lie around 10−3-10−4, 10−4-10−5, and 10−9-10−10.Figure 2

The Min and Max standards show the best results and poorest results in the 100 executions. For X(τ) category, the Min, Max, median, S.I range, and S.T.D values lie around 10−7–10−12, 10−1-10−2, 10−5–10−7, 10−5-10−6, and 10−1-10−2, respectively. For the category Y(τ), the Min, Max, median, S.I range, and S.T.D values lie around 10−4-10−5, 10−2-10−3, 10−4-10−5, 10−6-10−7, and 10−3-10−4, respectively. Likewise, the Min, Max, median, S.I range, and S.T.D values for the category Z(τ) lie around 10−5–10−11, 10−2-10−3, 10−4–10−7, 10−6-10−7, and 10−2-10−3, respectively. These calculated presentations found the worth and value of the proposed MWNN-GA-IPA to solve the nonlinear SIR dengue fever system. One can establish through the achieved results that the MWNN-GA-IPA is stable and precise.Table 2

## 4. Conclusions

The current investigations are linked to design a neural network based on Morlet wavelet (MWNN) function for solving the nonlinear SIR dengue fever system based on dengue infection using the optimization procedures of global and local search approaches, i.e., GA-IPA. The nonlinear SIR dengue fever system is capable to evaluate through GA-IPA using the layer arrangement of Morlet wavelet neural networks taking 10 neurons. The overlapped results through MWNN-GA-IPA and the reference results show the good accuracy level to solve the nonlinear SIR dengue fever system based on dengue infection. The performance measures based on T.I.C, M.A.D, and E-VAF have been calculated satisfactorily. The statistical assessments for 100 independent trials using MWNN-GA-IPA in terms of minimum, S.I range, median, standard deviation, and maximum operatives further validate the worth and correctness of the proposed MWNN-GA-IPA. Furthermore, statistics analysis has been performed in the case of SIR dengue fever model based on dengue infection.In future, the proposed MWNN-GA-IPA is proficient to solve the biological nonlinear systems, singular higher order nonlinear systems, and fluid dynamic systems.
