Cplex slides

Slides from ISMP 2015 by CPLEX Optimization Studio engine developers

A number of developers from both engines (CPLEX and CPO) in CPLEX Optimization Studio were in Pittsburgh mid-July for the ISMP 2015 conference. The slides that they presented are available on the IBM Decision Optimization community at https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/W1a790e980a7d_49c5_963d_2965e5d01401/page/ISMP%202015

These presentations describe how CPO and CPLEX performance were improved in version 12.6.2:
- Handling of symmetries in LP
- Mathematical Programming with indicator constraints
- Failure-directed Search for Constraint-based Scheduling
- Accelerating the Development of Efficient CP Optimizer Models
- Max-Clique cuts
- Advances in CPLEX for Mixed Integer Nonlinear Optimization (12.6.2 is five times faster on MISCOP!)
- Advances in the CPLEX Distributed Solver
