Litoiu (2017), "Adaptive Cloud Deployment using Persistence Strategies and Application Awareness", IEEE Transactions on Cloud Computing, vol. 5, no. 2, pp. 277-290 (http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=7064811). We modify our earlier CloudOpt method for task deployment in clouds to handle dynamic changes in workload using penalties and rewards to encourage stable deployments and discourage thrashing.
A.U. Chaudhry, R.H.M. Hafez, J.W. Chinneck (2016), “Realistic Interference-Free Channel Assignment for Dynamic Wireless Mesh Networks Using Beamforming”, Ad Hoc Networks, vol. 51, pp. 21-35. Available online at http://www.sciencedirect.com/science/article/pii/S1570870516301937 This paper develops the first channel assignment method for wireless mesh networks that incorporates beamforming in the conflict graph and matrix. This reduces the number of channels required significantly.
A.U. Chaudhry, J.W. Chinneck, R.H.M. Hafez (2016), “Fast Heuristics for the Frequency Channel Assignment Problem in Multi-Hop Wireless Networks”, European Journal of Operational Research, vol. 251, pp. 771-782, DOI: http://dx.doi.org/10.1016/j.ejor.2015.12.016. Channel assignment in wireless networks can be cast as a minimum colouring problem, but this does not account for cumulative interference. We develop fast algorithms for this extended colouring problem that are orders of magnitude faster than an exact solution method while consistently returning near-optimum results.

Chinneck (2015), “On the Impact of Interference Models on Channel Assignment in Multi-Radio Multi-Channel Wireless Mesh Networks,” Ad Hoc Networks, vol. 27, pp. 68-80. The interference model assumed in channel assignment significantly affects the results. More frequency channels are needed when the interference model is more realistic than commonly assumed.
W. Ibrahim, M. Shousha, J.W. Chinneck (2015), “Accurate and Efficient Estimation of Logic Circuits Reliability Bounds”, IEEE Transactions on Computers, vol. 64, no. 5, pp. 1217-1229. We develop a method to estimate the reliability bound for large and complex circuits. The method is fast and highly accurate in finding the set of input values that produces the lowest reliability.

Hafez (2013), “On the Number of Channels Required for Interference-free Wireless Mesh Networks”, EURASIP Journal on Wireless Communications and Networking 2013:229 (14 September 2013). Online at http://jwcn.eurasipjournals.com/content/2013/1/229. We develop a method for assigning channels in a wireless mesh network so that throughput is maximized, there is no interference, and the number of distinct channels is small.
H. Mahmoud and J.W. Chinneck (2013), "Achieving MILP Feasibility Quickly Using General Disjunctions", Computers and Operations Research, vol. 40, no. 8, pp. 2094-2102. Preprint version. Appendix. We show that oblique disjunctions that branch on linear combinations of variables can reduce the time to find the first integer-feasible solution in hard mixed-integer linear programs. We develop new ways to construct the general disjunctions and methods for deciding when they should be used.
L. Smith, J.W. Chinneck, and V. Aitken (2013), “Constraint Consensus Concentration for Identifying Disjoint Feasible Regions in Nonlinear Programs”, Optimization Methods and Software, vol. 28, no. 2, pp. 339–363. Preprint version. There may be multiple disjoint feasible regions in a constrained nonlinear program. We improve on multi-start methods for global optimization by using Constraint Consensus to quickly explore the variable space to find the feasible regions before launching an expensive local solver. Our solutions are more efficient because we usually launch the local solver only once near each feasible region.
L. Smith, J.W. Chinneck, V. Aitken (2013), “Improved Constraint Consensus Methods for Seeking Feasibility in Nonlinear Programs”, Computational Optimization and Applications, vol. 54, no. 3, pp. 555-578. DOI: http://dx.doi.org/10.1007/s10589-012-9473-z. Preprint version. We develop several improvements to the Constraint Consensus method for quickly finding near-feasible points in nonlinear programs: (i) a simple new way of constructing the consensus vector, (ii) a predictor-corrector method, (iii) a better way of selecting the output point, and (iv) better ways of selecting the subset of violated constraints to operate on at each iteration, which is especially effective when used in conjunction with barrier method local solvers. We also investigate quadratic feasibility vectors.
M. St-Hilaire, J.W. Chinneck, S. Chamberland, and S. Pierre (2012), “Efficient Solution of the 3G Network Planning Problem”, Computers and Industrial Engineering, vol. 63, no. 4, pp. 819–830. DOI: http://dx.doi.org/10.1016/j.cie.2012.05.004 We compare MIP and heuristic approaches for solving a difficult mobile telecommunications planning problem.
J.W. Chinneck (2012), "Integrated Classifier Hyperplane Placement and Feature Selection", Expert Systems with Applications, vol. 39, no. 9, pp. 8193-8203. Preprint version. Feature reduction and binary classifier hyperplane placement are normally treated as two distinct and separate processes. This paper combines the two using algorithms for solving the maximum feasible subset problem for a set of linear constraints. The method alternates between making progress on placing the separating hyperplane and adding or removing features. The empirical results are very good.
J. Pryor and J.W. Chinneck (2011), “Faster Integer-Feasibility in Mixed-Integer Linear Programs by Branching to Force Change”, Computers and Operations Research, vol. 38, pp. 1143–1152. Preprint version. Surprisingly, it turns out that if you want to reach a feasible solution for a MIP quickly, you should select branches that have the lowest probability of returning a feasible solution! This is because branching this way forces many other candidate variables to change their values simultaneously.
D.T. Wojtaszek and J.W. Chinneck (2010), “Faster MIP Solutions via New Node Selection Rules”, Computers and Operations Research, vol. 37, no. 9, pp. 1544-1556. Preprint version. DOI: http://dx.doi.org/10.1016/j.cor.2009.11.011 available online here. New heuristics for use in mixed-integer linear programming to determine when to backtrack, and which node to choose when backtracking, based on correlations and patterns commonly found in MIP solutions. Significantly improved solution speeds are demonstrated.

Chinneck (2008), "Improving Solver Success in Reaching Feasibility for Sets of Nonlinear Constraints", Computers and Operations Research, Vol. 35, pp. 1394-1411 (available online October 2, 2006 at www.sciencedirect.com). Preprint version in pdf. An improved initial point placement heuristic, coupled with the Constraint Consensus algorithm for point improvement provides starting points that greatly increase the success of various nonlinear solvers in reaching feasibility.
J. Patel and J.W. Chinneck (2007), "Active-Constraint Variable Ordering for Faster Feasibility of Mixed Integer Linear Programs", Mathematical Programming Series A, vol. 110, pp. 445-474. (pdf) You can reach feasibility for MIPs much faster by selecting the branching variable based on its impact on the active constraints in the parent LP relaxation, instead of using the traditional approach of selecting the branching variable based on its impact on the objective function.

J.W.Chinneck and K. Ramadan (2000), "Linear Programming with Interval Coefficients", Journal of the Operational Research Society, vol. 51, pp. 209-220. If the coefficients of your linear program are only approximately known, then how can you solve the LP? We present a method for finding the best optimum and the worst optimum when the coefficients are only known within specified intervals.

J.W. Chinneck, (1996), "An Effective Polynomial-Time Heuristic for the Minimum-Cardinality IIS Set-Covering Problem", Annals of Mathematics and Artificial Intelligence, vol. 17, pp. 127-144. Despite the title, this paper is about finding the smallest number of constraints to remove from an infeasible LP such that the remaining set of constraints is feasible. This is the same as finding the maximum cardinality feasible subset of constraints from among the original infeasible set. The problem is NP-complete, but the paper describes a remarkably effective polynomial-time heuristic. This has some surprising applications, including a way to train neural networks, and to linearly classify data.
