1 Answer1. This can be done via linear programming. Consider a set of linear inequalities A x ≤ b, together with an additional inequality c T x ≤ d. We wish to know if the constraint c T x ≤ d is redundant. c T x ≤ d + 1. The constraint c T x ≤ d is implied by A x ≤ b if the above linear .

The problem here is that y++ ends up being evaluated twice! The nasty consequence is that after this expression, y will have a value of 12 rather than the expected 11. This can be a real pain to debug! Multiline macros Until now, we've seen only short, one line macros (possibly taking advantage of the semicolon to put multiple statements on one ...

Guide to the columns: Linear/NonLinear: Linear solvers can only be used on problems where the adjustable cells appear linearly in the problem. If this is not the case, the linear solvers are very likely to return meaningless results. If a linear solver is used, there is the option to run a "Linearity Check" after the solve, which tries to make sure the problem was indeed linear.
