Example 1

The example is convex and involves a single objective function, simple bounds on the design variables, a nonlinear inequality constraint, and a linear equality constraint. The objective is

    

The constraints are

  

A feasible initial guess is

    

with corresponding value of the objective

    

The global minimizer is

    

with

    

 

example1.pds               

dv x1 x2 x3
ob f
ic c1
ec c2

example1.ini

x1 = 0.1
x2 = 0.7
x3 = 0.2
bl = zeros(3,1)

example1.sim

f = (x1+3*x2+x3)^2 + 4*(x1-x2)^2
c1 = x1^3-6*x2-4*x3+3
c2 = 1-x1-x2-x3
