Linear optimization.

Linear Optimization often goes by the name Linear Programming (LP). The word "Programming" should not be confused with computer programming which in fact it antedates. As originally used, the term refers to the timing and magnitude of actions to be carried out so as to achieve a goal in the best possible way.

Linear optimization. Things To Know About Linear optimization.

For the standard maximization linear programming problems, constraints are of the form: ax + by ≤ c a x + b y ≤ c. Since the variables are non-negative, we include the constraints: x ≥ 0 x ≥ 0; y ≥ 0 y ≥ 0. Graph the constraints. Shade the feasible region. Find the corner points. To demonstrate the minimization function, consider the problem of minimizing the Rosenbrock function of N variables: f(x) = N − 1 ∑ i = 1100(xi + 1 − x2i)2 + (1 − xi)2. The minimum value of this function is 0 which is achieved when xi = 1. Note that the Rosenbrock function and its derivatives are included in scipy.optimize.This work addresses inverse linear optimization, where the goal is to infer the unknown cost vector of a linear program.
