Should have used TDD/BDD, developed some Gherkin test cases, and used those to develop some JUnit automated tests before starting on the implementation. Oh, and each class -- for the solver, coefficients, variables, etc. -- needs to leverage dependency injection so they can be properly mocked in the tests...
I'm reminded of a story about Kent Beck or somebody, one of the big TDD gurus, who wanted to get a microcontroller to draw something on the screen or something. So he first wrote the program in Java, being sure to employ proper TDD principles, and then hand-translated the Java code to microcontroller assembly or something. But this was feted as a win for TDD and evidence that TDD can be used for anything and therefore should be used for everything. The details of the story are vague, and I can't source it right now, but I know it exists. Some Hackernews is bound to dig up a link, they usually do when I make an obscure reference.
