The user must submit a model in GAMS
format to solve a second order cone problem (SOCP).
For security purposes, the model
submitted must adhere to the following conventions:
If you are unfamiliar with GAMS, the

The NEOS Server initially limits the amount of output generated in the listing file by turning off the symbol and unique element list, symbol
cross references, and restricting the rows and columns listed to zero. This behavior can be changed by specifying the appropriate options
in the model file. See the
documentation on the
modeling language for further information.
Note: An email address is required for any submissions that use CPLEX. This email address will be forwarded to IBM
