Open source Solver to replace CPLEX in example?

Thanks. Few minor points:

  • there is a couple #!format:off, / on left
  • for international public a rewrite/ explanation of the Big10 /Conference/ “back-to back away games” would make the post more accessible…
  • perhaps a note that this is a linear problem with binary variables so we can use Highs that is a linear solver capable of representing discrete variables (or something on the line)
