25Cand
25Cand is a fictional open-source framework designed to illustrate principles of constraint-based problem solving. The name refers to its design around exploring up to 25 candidate options at each decision point.
The framework offers a modular architecture with three core components: a candidate manager that maintains the
Typical use cases include scheduling, resource allocation, and puzzle solving, as well as teaching concepts in
Development and reception. While portrayed as accessible and easy to prototype with, 25Cand is not intended
Limitations include limited scalability beyond hundreds of variables; it may underperform compared to specialized solvers on
