Abstract

Step fixed-charge transportation problem is an extended version of the fixed charge transportation problem, is one of the most important problems in transportation research area. To tackle such an NP-hard problem, we present Gravitational Search Algorithm (GSA). We solve the randomly generated problems by GSA and also with Genetic Algorithm (GA) to compare them. The obtained results show the proficiency of GSA comparison with GA.
