hola;

PDL, above, is great, but lacks a number of LP specific thingies. chunlou suggested the Math::LP at Re: Re: Minimax / AlphaBeta harness, which i think works on unix, tho i had problems getting it to compile. it harnesses one of the faster LP engines.

there is also the gnu linear programming toolkit, sadly yet to find a perl harness. this also solves constraint satistaction probs like n-queens, and other prob. categories. links to that and other potentially useful LP engines are in the above thread.

best of luck,
