R: Quadratic programming/ Isotonic regression
r,mathematical-optimization,minimization,quadratic-programming
Given the similarities of the optimization problem here to your previous question, I will borrow some language directly from my answer to that question. However they are quite a bit different (the previous problem was a linear programming problem and this is a quadratic programming problem, and the constraints differ),...
Constrained quadratic optimization with the quadProg library
r,mathematical-optimization,quadprog,quadratic-programming
You can do this with the solve.QP function from quadprog. From ?solve.QP, we read that solve.QP solves systems of the form min_b {-d'b + 0.5 b'Db | A'b >= b0}. You are solving a problem of the form min_w {-A'w + pw'Cw | w >= 0, 1'w = 1}. Thus,...
How to convert quadratic to linear program?

Models in this form are actually called bilinear optimization problems. The typical approach to linearizing bilinear terms is through something called the McCormick envelope. Consider variables x and y, where you want x*y in the objective of your maximization problem. If we assume x and y are bounded by xL...
