The NEOS Server offers the IBM
ILOG CPLEX Optimizer for the solution of linear programming (LP), mixed-integer
linear programming (MILP), and second-order conic programming (SOCP) problems.
Acceptable input formats for CPLEX on the NEOS server include AMPL, GAMS,
LP, MPS, and NL formats.
Details on CPLEX can be found on the IBM

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
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
As an alternative to NEOS, you may try the IBM Decision
Optimization Cloud for drag and drop solving.
