First official Open Source Project is a Delphi (Object Pascal) implementation of the Delta Blueincremental dataflow constraint solver. What is a incremental dataflow constraint solver?Simply put, it maintains relationships between variables and when a variable changes, automatically computes which variables are dependant and what their new values should be. For example: Given the constraint A + B = C, when either A or B changes, C will be recalculated; But if C changes, Delta Blue will also recalculate A or B depending on the strength of the constraint. |
