Abstract: A computer-implemented fraud detection system comprises a processor and memory storing computer-readable instructions for causing a computer to perform a method for determining potentially fraudulent records. The method performed by the computer comprises executing a trial fraud detection strategy routine on historic records in a database, the trial detection strategy comprising multiple rules including at least one weighting factor. The method further includes calculating an efficiency of the trial fraud detection strategy based on the multiple rules and executing an iterative routine to optimize adjusting the at least one weighting factor. An adjusted fraud detection strategy that incorporates the adjusted weighting factor is set.
