Abstract

In this paper, we have developed a method from which we can determine the exact optimal solution to geometric programming problems (GPPs). The method is based on the determination of exact rows of the optimal matrix in a GPP. The optimal matrix is the final matrix used to determine the optimal primal decision variables that satisfy the optimal objective function. This matrix is very important as it eliminates the rule of thumb and enables the accuracy of the solution to GPPs.
