Fractional programming is an interesting subject appeared in many types of optimization problems. For
example, it can be used in engineering and economics to minimize a ratio of functions between a given period
of time and a utilized resource in order to measure the efficiency or productivity of a system. In these types of
problems the objective function is usually given as a ratio of functions in fractional programming form (see
Optimization problems with minimax type functions arise in the design of electronic circuits, however mini-
max fractional problems appear in the formulation of discrete and continuous rational approximation problems
with respect to the Chebyshev norm , in continuous rational games , in multiobjective programming ,
in engineering design as well as in some portfolio selection problems discussed by Bajona-xandri and Martinez-
