DMCommunity.org posted the challenge “Mr Bates vs The Post Office”. I applied Rule Solver to demonstrate how to solve this challenge using several decision tables. Link

Then I decided to ask GenAI to produce a solution for this challenge using JavaSolver API. I was a bit surprised that Copilot is quite familiar with JavaSolver It quickly generated for me a Java program for a simple Arithmetic problem similar to this one. Then I gave the text of this Challenge in plain English, and Copilot generated a very good working solution for this challenge as well! Here it is: https://dmcommunity.org/wp-content/uploads/2025/03/challenge2025feb.copilot.pdf
