Neural Networks are powerful tools for classification and Regression, but it is difficult and time consuming to determine the best architecture for a given problem. In this paper two evolutionary algorithms, Genetic Algorithms (GA) and Binary Particle Swarm Optimization (BPS), are used to optimize the architecture of a Multi-Layer Perceptron Neural Network (MLP), in order to improve the predictive power of the credit risk scorecards. Results show that both methods outperform the Logistic
