Semi-infinite Multiobjective Fractional Programming I
2017In this chapter, we first present three new classes of generalized convex functions involving Hadamard directional derivatives, namely, (strictly) (\(\mathcal {F},\) \(\beta ,\) \(\phi ,\) \(\rho ,\) \(\eta ,\) \(\theta ,\) \(\mu \))-Hd-univex functions, (strictly) (\(\mathcal {F},\) \(\beta ,\) \(\phi ,\) \(\rho ,\) \(\eta ,\) \(\theta ,\) \(\mu ...

Duality in Fractional Programming
1997In mathematical programming, the duality theory takes a central place. In this theory, to a given problem, named “primal”, one associates another problem, named “dual”, and the relationship between the two problems is used to highlight the properties of the optimal solutions of both problems. An important consequence of the duality principle is that if

Fractional and complex programming
1978A number of applications lead to constrained minimization problems, in which the objective function, to be minimized or maximized, is a quotient, f(x)/g(x), of two functions. Such a problem is called a fractional programming problem. In particular, it is a linear fractional programming problem if f and g are linear, or affine, functions, and the ...
