- Abstract:
-
This paper introduces the concept of multiple traveling salespersons problem (MTSP) and a chromosome encoding design method for solving the MTSP using genetic algorithm. In order to reduce the cost of redundant solution, two traditional chromosome design methods (single and double chromosome designs) are proposed, as well as the current two-part chromosome encoding design. Then the concept of relative solution space is introduced to quantitatively compare the relative size order of spaces for different solutions. Then on based on the relative solution space, the relative size order of the solution spaces of three chromosome-encoding designs are analyzed under an infinite limit. Subsequently, the relative size order of the solution spaces is analyzed individually when the relationship presents different situations between the number of travelers and the number of cities. The theoretical results of the quantitative analysis on the search space given in this paper are of great significance in guiding engineering applications and solving practical problems.
