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
Additional information on all IBM software available to academics can be

The user must submit a model in CPLEX
LP format to solve a linear program.
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.
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.
When using the XML-RPC interface, you must add the following line into the XML file that is sent to NEOS:
