# Current problems
## Different results between lp_solve and glpk for Java-based generated ILPs
- Java-based System-Generator creates a system plus request
- Java-based ILP-Generator takes system plus request, and creates and ILP for lp_solve
- own python script changes syntax to match expected format for glpk
- lp_solve and glpk find different solution, with different objective
- example: 10_10_1_2, lp_solve 117.00000000, glpk 95.52083074
- glpk returns bad values for binary vars, e.g. 0.348485
## Slow Larceny
- Although Larceny compiles to machine code, it runs significantly slower than racket
- For ILP-Generaration, it should be the attribute ilp-nego-hw and ilp-nego-hw0
