The NEOS Server offers the IBM ILOG CPLEX
Optimizer for the solution of mixed-integer linear programming (MILP) problems that can be modeled in

Using the NEOS Server with CPLEX/LP
The user must submit a model in
CPLEX LP format
to solve an MILP.
The user may optionally specify two files. The first file may contain
a list of CPLEX commands that the user would like executed before the
LP file is read and the optimize command is executed. The second file may contain a list of CPLEX commands that will be executed after the CPLEX optimize command.
The user need not (or should not) include the
optimize commands in these files. The CPLEX
xecute command is not allowed in these files.
Documentation on the CPLEX parameters that may set is located in the
CPLEX Optimization Studio Knowledge Center.
Note: An email address is required for any submissions
that use CPLEX. This email address will be forwarded to IBM
and may be used by IBM for promotional purposes.
If using the XML-RPC interface, you must add the line <email>firstname.lastname@example.org</email> into the XML file that is sent to NEOS.
As an alternative to NEOS, you may try the
Optimization Cloud for drag and drop solving.
