Abstract
This paper considers a fractional functionals programming problem of the type: maximize z= ∑ 1 nc j|x j|+α ∑ 1 nd j|x j|+β subject to Ax=b, x is unrestricted. In general, adjacent extreme point (simplex-type) methods [Naval Res. Logist. Quart. II (1964) 135] cannot be used to solve this class of problems. However, this work presents the conditions under which simplex-type algorithms can be used to arrive at an optimal solution for a fractional programming problem with an absolute value objective function.
