- Jakob Witzig
This reader allows to parse a new objective function the style of CPLEX .lp files.
The lp format is defined within the CPLEX documentation.

writes problem to file
- Parameters
-
| scip | SCIP data structure |
| file | output file, or NULL if standard output should be used |
| name | problem name |
| transformed | TRUE iff problem is the transformed problem |
| objsense | objective sense |
| objscale | scalar applied to objective function; external objective value is extobj = objsense * objscale * (intobj + objoffset) |
| objoffset | objective offset from bound shifting and fixing |
| vars | array with active variables ordered binary, integer, implicit, continuous |
| nvars | number of mutable variables in the problem |
| nbinvars | number of binary variables |
| nintvars | number of general integer variables |
| nimplvars | number of implicit integer variables |
| ncontvars | number of continuous variables |
| conss | array with constraints of the problem |
| nconss | number of constraints in the problem |
| result | pointer to store the result of the file writing call |
