Algorithm na kwayoyin halitta

Algorithm na kwayoyin halitta (PBGA) algorithm ne na kwayoyin halittar don juyin halitta wanda F. Bellas da RJ Duro suka kirkira a cikin Ƙungiyar Haɗin Kai don Binciken Injiniya (GII) a Jami'ar Coruña, a Spain. Yana haifar da Cibiyoyin sadarwa na wucin gadi (ANN) masu girman gaske waɗanda aka tsara su cikin jerin kwayoyin halitta don gina na'urar ANN ta asali. Kowane ɗayan waɗannan tubalan yana gaba da mai gabatar da kwayar halitta wanda ke aiki a matsayin mai kunnawa / kashewa wanda ke ƙayyade ko za a bayyana wannan ɗayan ko a'a.F. Bellas, R. J.

 Abubuwan PBGA na asali 
Ƙungiyar asali a cikin PBGA shine neuron tare da duk haɗin shigarwa kamar yadda aka wakilta a cikin adadi mai zuwa:

kwayar halitta ta asali ita ce saiti na ainihin ma'auni mai daraja wanda ke biye da sigogi na neuron kuma ya ci gaba da wani yanki mai daraja wanda ya ƙayyade darajar kwayar halitta mai gabatar da ita kuma, saboda haka, furcin naúrar. Ta hanyar haɗa raka'a na wannan nau'in za mu iya gina dukkan cibiyar sadarwa.

Tare da wannan ƙididdigar an ɗora shi cewa bayanin da ba a bayyana ba har yanzu ana ɗaukar shi ta hanyar kwayar halitta a cikin juyin halitta amma an kare shi daga matsin lamba kai tsaye, yana kiyaye wannan hanyar bambancin a cikin yawan jama'a, wanda ya kasance tushen ƙira don wannan algorithm. Sabili da haka, an kafa bambanci tsakanin sararin bincike da sararin bayani, yana ba da izinin bayanan da aka koya kuma an sanya su cikin wakilcin kwayar halitta don a adana su ta hanyar kashe kwayoyin halitta.

 Sakamakon 
An gabatar da PBGA ne da farko  a cikin filin robotics mai cin gashin kansa, musamman a cikin ilmantarwa na ainihi na samfuran muhalli na robot.

An yi amfani da shi a cikin tsarin fahimta na Multilevel Darwinist Brain (MDB) wanda aka haɓaka a cikin GII don ilmantarwa na ainihi a kan layi. A cikin wani takarda  an nuna yadda aikace-aikacen PBGA tare da ƙwaƙwalwar ajiya ta waje wanda ke adana samfuran duniya da aka samu, shine mafi kyawun dabarun daidaitawa a cikin mahalli mai ƙarfi. 

Kwanan nan, PBGA ta samar da sakamakon da ya fi sauran algorithms na juyin halitta a cikin matsalolin da ba na tsayawa ba, inda aikin motsa jiki ya bambanta a lokaci.
