We report a measurement of the top quark mass $M_t$ in the dilepton decaychannel $t\bar{t}\to b\ell'^{+}\nu'_\ell\bar{b}\ell^{-}\bar{\nu}_{\ell}$.Events are selected with a neural network which has been directly optimized forstatistical precision in top quark mass using neuroevolution, a techniquemodeled on biological evolution. The top quark mass is extracted from per-eventprobability densities that are formed by the convolution of leading ordermatrix elements and detector resolution functions. The joint probability is theproduct of the probability densities from 344 candidate events in 2.0 fb$^{-1}$of $p\bar{p}$ collisions collected with the CDF II detector, yielding ameasurement of $M_t= 171.2\pm 2.7(\textrm{stat.})\pm2.9(\textrm{syst.})\mathrm{GeV}/c^2$.
