18th International Conference on Mathematical Optimization Theory and Operations Research, MOTOR 2019: 18th International Conference, MOTOR 2019, Ekaterinburg, Russia, July 8-12, 2019, Proceedings

The proceedings contain 49 papers. The special focus in this conference is on Mathematical Optimization Theory and Operations Research. The topics include: Local search approach for the medianoid problem with multi-purpose shopping trips; flow shop with job–dependent buffer requirements—a polynomial–time algorithm and efficient heuristics; pareto-based hybrid algorithms for the bicriteria asymmetric travelling salesman problem; simulated annealing approach to verify vertex adjacencies in the traveling salesperson polytope; less is more: Tabu search for bipartite quadratic programming problem; black-box optimization in an extended search space for sat solving; a control problem for parabolic systems with incomplete information; non-convex quadratic programming problems in short wave Antenna array optimization; best approximation of a differentiation operator on the set of smooth functions with exactly or approximately given fourier transform; feedback minimum principle for optimal control problems in discrete-time systems and its applications; estimates of the minimal eigenvalue of the controllability gramian for a system containing a small parameter; optimality conditions and numerical algorithms for hybrid control systems; on ellipsoidal estimates for reachable sets of the control system; problems of hard control for a class of degenerate fractional order evolution equations; feedback optimality conditions with weakly invariant functions for nonlinear problems of impulsive control; semi-supervised classification using multiple clustering and low-rank matrix operations; maximum diversity problem with squared euclidean distance; estimation of the necessary sample size for approximation of stochastic optimization problems with probabilistic criteria; splitting method with adaptive step-size; approximation algorithms for piercing special families of hippodromes: An extended abstract; preface.
