Yes, so you need to change the name of your class to AdaptiveSolver. :-)

It wouldn't be hard to add VariationalProblem and LinearSystem classes
which just hold the variables. We could even add solve() functions
which call the respective solvers. The only problem is that there will
then be 3 different ways to solve a problem:

  x = solve(A, b)
  x = solver.solve(A, b)
  x = LinearSystem(A, b).solve()

:-)

But that might be ok?
