In 1994 Lazard proposed an improved projection operation for cylindrical algebraic decomposition (CAD). For the proof he introduced a certain notion of valuation of a multivariate Puiseux series at a point. However a gap in one of the key supporting ...
McCallum-style Cylindrical Algebra Decomposition (CAD) is a major improvement on the original Collins version, and has had many subsequent advances, notably for total or partial equational constraints. But it suffers from a problem with nullification. ...
Proposed equality constraint and variable reduction strategy reduces equality constraints.Proposed equality constraint and variable reduction strategy also reduces the variables of COPs.Proposed strategy eliminates equality constraints that provide ...
