Ipopt (Interior Point OPTimizer, pronounced eye-pea-Opt)

|
|
Ipopt (Interior Point OPTimizer, pronounced eye-pea-Opt) is a software
|
|
package for large-scale, nonlinear optimization. It is designed to find
|
|
(local) solutions of mathematical optimization problems in the form:
|
|
|
|
min f(x)
|
|
x in R^n
|
|
|
|
s.t. g_L <= g(x) <= g_U
|
|
x_L <= x <= x_U
|
|
|
|
where f(x): R^n --> R is the objective function, and g(x): R^n --> R^m
|
|
are the constraint functions. The vectors g_L and g_U denote the lower
|
|
and upper bounds on the constraints, and the vectors x_L and x_U are
|
|
the bounds on the variables x. The functions f(x) and g(x) can be
|
|
nonlinear and nonconvex, but should be twice continuously
|
|
differentiable. Note that equality constraints can be formulated in
|
|
the above formulation by setting the corresponding components of g_L
|
|
and g_U to the same value.
