DMCommunity.org has already received five solutions for its Oct-2025 Challenge, which asks to help a web designer to select certain website features while satisfying budget and value constraints. What makes this simple problem interesting is that it involves two conflicting objectives: total value and total cost. Potential solutions are supposed to devise a rational way to trade them against each other.

The provided solutions were created using the following tools: Seeker, Pymoo, OPL CPLEX, Copilot, and OpenRules. I decided to add one more solution based on http://RuleSolver.com. This post https://lnkd.in/eYdJAHEE briefly analyzes all six solutions.
