Tree-seed algorithm (TSA) is a nature-inspired metaheuristic optimization algorithm.TSA was originally designed and introduced for solving continuous optimization problems.In this study, TSA was modified with transfer functions so as to solve binary optimization problems.Continuous search space was mapped to binary search space with transfer functions.Four S-shaped and four Vshaped transfer functions were used for discretization.Uncapacitated facility location problem (UFLP) is a pure binary optimization problem.In order to measure the performance, 15 different sized (small, medium, large and extra-large) UFLPs were solved with eight different binary TSAs in this study.Experimental results has shown that S-shaped transfer functions are better than V-shaped transfer functions on these problem sets.
