Solving the Traveling Salesman Problem by an Efficient Hybrid Metaheuristic Algorithm
The traveling salesman problem (TSP) is the problem of finding the shortest tour through all the nodes that a salesman has to visit. The TSP is probably the most famous and extensively studied problem in the field of combinatorial optimization. Because this problem is an NP-hard problem, practical large-scale instances cannot be solved by exact algorithms within acceptable computational times. ...

متن کاملLarge Combinatorial Optimization Problems: a Methodology for Hybrid Models and Solutions
Large Scale Combinatorial Optimization problems (LSCO) appear in numerous types of industrial applications (e.g. production scheduling, routing problems , nancial applications). They are NP-complete problems characterized by large sets of data, constraints and variables, and often have an impure structure. Tackling such problems successfully requires both experience and skill. The current trend...
متن کاملA hybrid metaheuristic using fuzzy greedy search operator for combinatorial optimization with specific reference to the travelling salesman problem
We describe a hybrid meta-heuristic algorithm for combinatorial optimization problems with a specific reference to the travelling salesman problem (TSP). The method is a combination of a genetic algorithm (GA) and greedy randomized adaptive search procedure (GRASP). A new adaptive fuzzy a greedy search operator is developed for this hybrid method. Computational experiments using a wide range of...
متن کاملA hybrid algorithm optimization approach for machine loading problem in flexible manufacturing system
The production planning problem of flexible manufacturing system (FMS) concerns with decisions that have to be made before an FMS begins to produce parts according to a given production plan during an upcoming planning horizon. The main aspect of production planning deals with machine loading problem in which selection of a subset of jobs to be manufactured and assignment of their operations to...
