![]() ![]() Then A (X) and B (X) are fine but for C (X) it must be in the form c (X) < 0 so you'll need to break it into two constraints of that form. In addition, all variables must be between 1 and 5 and the initial guess is x 1 = 1, x 2 = 5, x 3 = 5, and x 4 = 1. 1 Use the nonlcon parameter of fmincon (I'm assuming here your constraints are nonlinear). The product of the four variables must be greater than 25 while the sum of squares of the variables must also equal 40. Matlab Fmincon Optimization Example: Constrained Box Volume 33,381 views This video shows how to perform a simple constrained optimization problem with fmincon in Matlab. A good example is ’s 10.37 recitation problem. Reactor optimization example Now with the basic knowledge of using fmincon, let’s apply it to our reactor design domain. Please check it out if you want to know more. ![]() ![]() The variable values at the optimal solution are subject to (s.t.) both equality (=40) and inequality (>25) constraints. x fmincon(fun,x0,A,b,Aeq,beq,lb,ub,nonlcon) subjects the minimization to the nonlinear inequalities c(x) or equalities ceq(x) defined in nonlcon. Matlab tutorial has well covered typical ways of using fmincon to perform optimization. This problem has a nonlinear objective that the optimizer attempts to minimize. One example of an optimization problem from a benchmark test set is the Hock Schittkowski problem #71. , >=), objective functions, algebraic equations, differential equations, continuous variables, discrete or integer variables, etc. Mathematical optimization problems may include equality constraints (e.g. MATLAB can be used to optimize parameters in a model to best fit data, increase profitability of a potential engineering design, or meet some other type of objective that can be described mathematically with variables and equations. Optimization deals with selecting the best option among a number of possible choices that are feasible or don't violate constraints. ![]()
