Abstract: This paper presents an efficient algorithm for globally solving a generalized linear fractional programming problem. For establishing this algorithm, we firstly construct a two-level linear relaxation method, and by utilizing the method, we can convert the initial generalized linear fractional programming problem and its subproblems into a series of linear programming relaxation problems. Based on the branch-and-bound framework and linear programming relaxation problems, a branch-and-bound algorithm is presented for globally solving the generalized linear fractional programming problem, and the computational complexity of the algorithm is given. Finally, numerical experimental results demonstrate the feasibility and efficiency of the proposed algorithm.
