The eclipsing binary BUL-SC16 335 is one of the by-products of the OGLE (Optical Gravitational Lensing Experiment) survey in the direction of the galactic bulge. Its light curve shows a very short period (P ˜ 0.125 days), strong reflection effect and a sharp primary eclipse - suggesting this is a pre-cataclysmic variable like HW Vir, the prototype of a group of detached binaries containing a hot SdB-type primary and a cool stellar companion. We analyzed the light curve in the I and B bands using the Wilson-Devinney code. We applied a genetic algorithm together with the Downhill Simplex method to search for an optimum solution. We present the set of parameters obtained for the best fit model.
