Starting out with linear programming, I'm having some questions about canonical linear programs:
Do all linear programs have a canonical form? So far I couldn't figure an example stating otherwise.
Can a linear program have different (multiple) canonical forms? I guess the answer is yes. Are all forms equally good for solving the program? Is there any relevant difference?
A "basic feasible solution" is a feasible solution where the non-basic variables are equalled to 0. Is there only one "basic feasible solution" for each canonical linear program?
