An enhanced optimization technique based on evolution strategies is investigated and applied to the estimation of some unknown parameters that determine the shape and location of malignant breast tumors. The tumor reconstruction is achieved through the minimization of an error function defined between the measured information and the scattered data generated numerically. Our preliminary results show that using Cauchy's distribution in the evolutionary algorithm leads to a significant reduction in the CPU time required to estimate the shape and location of the tumor.
