REW format
The REW format is identical to the MPS
format, except in how objects are named when files are written. When
writing an MPS format file, the Gurobi optimizer refers to constraints
and variables using their given names. When writing an REW format
file, the Gurobi optimizer ignores the given names and instead refers
to the variables using a set of default names that are based on row
and column numbers. Specifically, column number j
gets name
C000j
, where the number of zeros is chosen to make the total
name length at least 8 characters. Similarly, row number i
gets name R000i
.
