[sage-support] Simplification of multivariable polynomial over a polynomial ring

2013-02-18 Thread Emmanuel
Hello, I want to work with multivariate polynomials over a multivariate polynomial ring (see below for the reason I want to do this). K.a,b=PolynomialRing(QQ, 2, order='lex') QM.X,Y,Z = PolynomialRing(K, 3, order='lex') However, I have problems when I want to simplify. Consider for example,

Hi, I found some answers myself. The memory usage can be found out with get_memory_usage() and there is a garbage collection that can be called manually via import gc gc.collect() so I could do something like import gc i=i+1 if (i%1==0): if get_memory_usage()3000:
