The NEOS Server offers LINDOGlobal for the solution of global
optimization problems and mixed-integer nonlinear-constrained problems in
AMPL and
GAMS formats.

LINDO Global finds guaranteed globally optimal solutions to general
nonlinear problems with continuous and/or discrete variables. The LINDO
global optimization procedure (GOP) employs branch-and-cut methods to break
a nonlinear programming model into a list of subproblems. Each subproblem is
analyzed; the result of the analysis is one of the following: a) the
subproblem is shown to not have a feasible or optimal solution, b) an
optimal solution to the subproblem is found, e.g., because the subproblem is
shown to be convex, or c) the subproblem is further split into two or more
subproblems, which are then placed on the list. Given appropriate
tolerances, a solution is returned that is provably globally optimal to the
tolerance.

LINDO Global is developed by Lindo Systems, Inc,
which offers the LINDO API. The LINDO API is a library of optimization solvers and mathematical
programming tools that allows users to create their own optimization
applications.

The problem must be specified in a model file. A data file and commands
files may also be provided. If the commands file is specified, it must
contain the AMPL solve command; however, it must not contain
the model or data commands. The model and data
files are renamed internally by NEOS.

The commands file may include option settings for the solver. To specify
solver options, add
