Abstract and PostScript version of 'Multi-Agent Planning Using an Abductive Event Calculus' in which a planning service module is incorporated into a constraint-logic framework to gain a strong sense of non-linearity.

Catalog of compilers: CLP(R) The implementation contains a built-in constraint solver which deals with linear arithmetic and contains a mechanism for delaying nonlinear constraints until they become linear. Since CLP(R) subsumes PROLOG, the system is also usable as a general-purpose logic programming language. There...Compiler-oriented development environment for constraint-logic applications with extended Prolog technology, persistent knowledgebase, constraint-handling facilities and parallelism. Runs on Unix/Linux, beta version for Windows 9x/NT/2000.

In many uses (interactive graphics, planning, document formatting, decision support), one must express preferences (soft constraints), and strict requirements (hard constraints).
