Webminimize c T x subject to A x = b. No other information is given. My solution is basically as follows: p ∗ = { ∞ if A x = b has no solution λ ⊤ b c = A ⊤ λ for some λ − ∞ if A x = b has infinitely many solutions (underdetermined) When A x = b has no solution the problem is … WebThere are some really fancy methods (such as “Mirror descent and nonlinear projected subgradient methods for convex optimization”, Beck and Teboulle) that specifically have methods for minimizing over the unit simplex. But these methods only use the gradient and not the Hessian. slang shirts
