Nowadays, due to the inherent complexity of the real optimization problems, it is a challenging issue to develop a solution algorithm to these problems. Single row facility layout problem (SRFLP) is an NP-hard problem of arranging a number of rectangular facilities with varying lengths on one side of a straight line with the aim of minimizing the weighted sum of the distances between all the facility pairs. In this work, the two new algorithms cuckoo optimization (CO) and forest optimization (FO) are applied and compared to solve SRFLP for the first time. The operators of these two algorithms are adapted according to the characteristics of SRFLP, and the results obtained are compared for two groups of benchmark instances of the literature. These groups consist of instances with the number of facilities less and more than 30. The results obtained from the two groups of instances show that the proposed cuckoo optimization algorithm (COA) has a better performance than the proposed forest optimization algorithm (FOA) in both aspects of finding the best solution and the computational time.
