  • Can Gurobi do nonlinear optimization?

    Gurobi is not a general purpose nonlinear programming solver, but it is able to handle certain nonlinear constraints by reformulating them into supported linear and/or quadratic constraints..

  • How does Gurobi Optimizer work?

    The Gurobi MIP and barrier optimizers include innovative shared-memory parallel algorithms that make use of all available cores and sockets.
    These algorithms are implemented to execute deterministically so that two runs on the same model produce identical results..

  • What does Gurobi optimization do?

    It can be used to solve optimization problems using any of the following forms: linear constraints, bound constraints, integrality constraints, cone constraints, and quadratic constraints..

  • What is convex function in machine learning?

    A function f is said to be a convex function if the seconder-order derivative of that function is greater than or equal to 0.
    Condition for convex functions.
    Examples of convex functions: y=eˣ, y=x\xb2.
    Both of these functions are differentiable twice..

  • Which algorithm is used in Gurobi?

    The Gurobi Mixed-Integer Programming solver (MILP and MIQP) utilizes an advanced pioneering branch-and-cut algorithm.
    The simplex and barrier solvers for LP and QP quickly and robustly solve models with millions of variables and constraints..

  • Gurobi is not a general purpose nonlinear programming solver, but it is able to handle certain nonlinear constraints by reformulating them into supported linear and/or quadratic constraints.
Dec 10, 2020I am wondering which algorithm/optimizer Gurobi uses to solve 'general' convex optimization (linear objective with quadratic and linear 

Is Gurobi a convex model?

Gurobi 9

0+ supports general non-convex quadratic constraints and objective functions, including bilinear and quadratic equality constraints

Non-convex models are typically harder to solve than convex models

If possible, consider reformulating the model into a convex problem

What types of constraints can Gurobi solve?

Gurobi versions 9

0 and later can solve models with linear constraints, quadratic constraints (both convex and non-convex), and second-order cone constraints

This can involve any combination of continuous and integer variables

The canonical form is:

Why is Gurobi a good choice for a non-linear optimization model?

Gurobi allows you to formulate non-linear optimization models

If these models adhere to certain properties, they are called convex

This is an important property to know about when solving an optimization model, because convexity can be algorithmically exploited to solve the model faster
