چکیده

For the p-median problem we study complexity of finding a local minimum in the worst and the average cases. We introduce several neighborhoods and show that the corresponding local search problems are PLS-complete. In the average case we note that standard local descent algorithm is polynomial. A relationship between local optima and 0–1 local saddle points is presented.

A reactive bone route algorithm for solving the traveling salesman problem

The traveling salesman problem (TSP) is a well-known optimization problem in graph theory, as well as in operations research that has nowadays received much attention because of its practical applications in industrial and service problems. In this problem, a salesman starts to move from an arbitrary place called depot and after visits all of the nodes, finally comes back to the depot. The obje...

Iterated Local Search Algorithm for the Constrained Two-Dimensional Non-Guillotine Cutting Problem

An Iterated Local Search method for the constrained two-dimensional non-guillotine cutting problem is presented. This problem consists in cutting pieces from a large stock rectangle to maximize the total value of pieces cut. In this problem, we take into account restrictions on the number of pieces of each size required to be cut. It can be classified as 2D-SLOPP (two dimensional single large o...

مدل حل مبتنی بر جستجوگر محلی ژنتیک برای مساله زمان بندی استقرار کارگاهی تعمیم یافته با زمانهای عملیات قابل کنترل

Although incorporating complexities and flexibilities of real world manufacturing systems into classic scheduling problems results in problems with greater complexity, it has immense theoretical and practical importance due to its impressive effect on system performance. In this research, three basic assumptions of a job shop scheduling problem have been revised to develop a model with three ty...

On the Implemention of a Swap-Based Local Search Procedure for the p-Median Problem

We present a new implementation of a widely used swap-based local search procedure for the p-median problem. It produces the same output as the best implementation described in the literature and has the same worst-case complexity, but, through the use of extra memory, it can be significantly faster in practice: speedups of up to three orders of magnitude were observed.
