Abstract

A computer-implemented method, apparatus, and article of manufacture optimizes publication layouts using a genetic algorithm approach. In a timely manner, the computer-implemented invention generates and evaluates a large number of publication layouts and selects the optimum layout. The optimal layout has an optimal relationship between the placement of advertisements and stories on the pages of the publication, the maximization of revenues, and the minimization of printing costs.
