process_modeling

This folder contains an example of using parametric objects to represent and restore shared variables between sets of constraints that are stored in different objects. This solution is applied to process modeling where constraints are used to represent run dependencies between processes. Part of the process description is a set of finite domain constraints describing how many times the process can or must be executed. An object parameter is used to provide access to the process constraint variable. See the comments in the process_modeling.lgt file for further details.

This example can be run using B-Prolog, ECLiPSe, GNU Prolog, SICStus Prolog, SWI-Prolog, or YAP as the backend compiler (by using an ugly solution thanks to the lack of standardization of CLP(FD) constraint libraries).

Load the example:

logtalk_load(process_modeling(loader)).

Compute the number of times that process b can be executed and its dependencies:

%%table
process_model::solve([b(B)], Dependencies).

Compute the number of times that process c can be executed and its dependencies:

%%table
process_model::solve([c(C)], Dependencies).
