Optimization cost function definition
WebConstrained optimization. In mathematical optimization, constrained optimization (in some contexts called constraint optimization) is the process of optimizing an objective function with respect to some variables in the presence of constraints on those variables. The objective function is either a cost function or energy function, which is to ... WebPiecewise-linear function f :Rn → R is (convex) piecewise-linear if it can be expressed as f(x)= max i=1,...,m (aT i x+bi) f is parameterized by m n-vectors ai and m scalars bi x aT i x+bi f(x) (the term piecewise-affine is more accurate but less common)
