This problem is generalized to the problem of answering queries about arbitrary sets using a certain query language. Furthermore an efficient algorithm for solving this problem for sets described by arbitrary non-linear polynomials is presented. =howpublished= Proceedings of IMACS ACA, Linz - Hagenberg, 1996 =location= 2 =owner= 2 =source= 3 =reftype= 14
