Overview

A parallel solver for constraint hierarchy which introduces hierarchy in terms of strength of constraints.

System Architecture

Function

Hierarchical constraint parallel solver P-CHAL is based on new programming paradigm "constraint programming" which allows user a high-level description in problem solving. P- CHAL is a parallel consrraint solver which manipulates various strength of constraints in various domains.

  1. Parallel Solving of Constraint Hierarchy:
    P-CHAL reduces computational costs by a bottom-up calculation of maximal consistent sets and parallel processing of GDCC.
  2. Constraints Solvers for Various Domains
    P-CHAL provides constraint solvers for non-linear algebraic equations and Boolean equations for various domains of users. User can specify various strength for these constraints.
