Week 3 Flashcards
What is branch & Bound
Constant Precision
is only relaly for non linear problems
Automatic Scaling
if you are using very small and very large numbers, this should be checked on
Integer optimality
the max% difference solver should accept between the best integer solution found and the best known bound on the true optimal objective value BEFORE STOPPING
What is Binary Integer programming BIP
Categorical decisions, YES=1, NO=0
Examples of BIP
-> Capital Budgeting (Invest or Dont)
-> Fixed Cost (An all or nothing cost! that is not variable on per unit production)
-> Location Planning/Set Covering (Here, or Not)
when changing cells are both integer and non integer?
MIXED INTEGER PROGRAMMING
Set Covering
BASICALLY ITS A EYS OR NO!
How to do set covering
- copy all the set! make a new section
2.in this new section have the YES or NO - Declare decision variables (what choice are you making?) (BINARY)
- now add a new area where you have a “covered?” as a binary area (AS A DECISION VARIABLE) AGAIN! this will prevent double counting
