WebForward Checking Algorithm /* this method just checks the constraint C */ FCCheck (C,x) // C is a constraint with all its variables already // assigned, except for variable x. for d := each member of CurDom[x] if making x = d together with previous assignments to variables in scope C falsifies C then remove d from CurDom[x] WebA part of algorithms for CSP are forward algorithms. They are used to check consistency and constraint propagation. The most famous forward algorithm, is forward checking algorithm (FCA). In this article we are going to introduce FCA and suggest two algorithms to improve efficiency of forward.
