Those that solve artificially simplified problems where quantum advantage is meaningless. Those that provide no genuine quantum advantage when all costs are properly accounted for. This critique is ...

You can get solutions with the least-squares method even if overdetermined systems (the number of equations is greater than the number of variables). It is written in C++. C++11 or later is required.

Use tiles to represent variables and constants, learn how to represent and solve algebra problem. Solve equations, substitute in variable expressions, and expand and factor. Flip tiles, remove zero ...
