We study time-consistency of optimization problems, where we say that an problem is time-consistent if its optimal solution, or the policy for choosing actions, does not depend on when solved. Time-consistency a minimal requirement decisions made based solution to be rational. show return can gain by taking "optimal" actions selected solving time-inconsistent surely dominated could "suboptimal"...

The Charged System Search (CSS) is combined to chaos to solve mathematical global optimization problems. The CSS is a recently developed meta-heuristic optimization technique inspired by the governing laws of physics and mechanics. The present study introduces chaos into the CSS in order to increase its global search mobility for a better global optimization. Nine chaos-based CSS (CCSS) methods...

Recently, many meta-heuristic algorithms are proposed for optimization of various problems. Some of them originally are presented for continuous optimization problems and some others are just applicable for discrete ones. In the literature, sizing optimization of truss structures is one of the discrete optimization problems which is solved by many meta-heuristic algorithms. In this paper, in or...
