From: Maki Takahashi on 23 Sep 2009 18:13 Hi I'm trying to solve a system of polynomial equations using various inbuilt functions namely Solve[] and Reduce[]. When ever I try this the kernel crashes as it runs out of memory. I was then advised to manually try to solve it by calling GroebnerBasis[] but this also resulted crashed the kernel.... is there a way to control any memory leaks with mathematica? cheers Maki

You've not supplied any detail. Any sufficiently large polynomial system will cause any machine to run out of memory regardless of whether memory leaks exist in Mathematica or not. Without knowing how much memory you have, details of your system and details of the polynomial system you are attempting to solve, it is impossible to determine the best approach for avoiding the problems you are encountering. And without these details, it is not clear whether the problems you are encountering constitute a bug such as a memory leak or is simply a limitation of the system you are using. |
