RLP format
The RLP format is identical to the LP
format, except in how objects are named when files are written. When
writing an LP format file, the Gurobi Optimizer refers to constraints
and variables using their given names. When writing an RLP format
file, the Gurobi Optimizer ignores the given names and instead refers
to the variables using names that are based on variable or constraint
characteristics. The constraint name depends solely on the associated
row number: row i gets name ci. The variable name
depends on the type of the variable, the column number of the variable
in the constraint matrix, and the number of non-zero coefficients in
the associated column. A continuous variable in column 7 with column
length 2 would get name C7(2), for example. A binary variable
with the same characteristics would get name B7(2).
