This paper introduces an interval valued linear fractional programming problem (IVLFP). An IVLFP is a linear frac-tional programming problem with interval coefficients in the objective function. It is ...
A routine written in IML to solve this problem follows. The approach appends slack, surplus, and artificial variables to the model where needed. It then solves phase 1 to find a primal feasible ...
This is a preview. Log in through your library . Abstract The basic properties are stated of a linear programming problem with a linear objective function having quadratic constraints whose associated ...
The study explored the relationship between students' attitude towards, and performance in mathematics word problems (MWTs), mediated by the active learning heuristic problem solving (ALHPS) approach.
