This paper presents a determined global optimization algorithm for solving linear fractional programming. After obtaining an equivalent problem of the initial problem through trasformation, then by using relaxation technique, the equivalent problem can be reduced to a sequence of linear programming problems. The proposed algorithm will be convergent to the global optimal solution by means of the subsequent solutions of the series of linear programming problems. Convergence of the algorithm is established and numerical results are given to show the feasibility and effectiveness.
