Abstract
The two-dimensional wind-tree model with particles with four allowed v elocities, which can scatter off obstacles with internal degrees of fr eedom, is solved exactly. Depending on initial conditions the distribu tion functions and entropy of obstacles can display a nonmonotonic tim e dependence with over- and underpopulations followed by transient rel axation.
