Solution Architecture

FICO® Xpress Optimization

FICO® Xpress Optimization is comprised of four components:

  1. FICO® Xpress Insight enables businesses to rapidly deploy optimization models as powerful applications. It allows business and other users to work with models in easy-to-understand terms. 
  2. FICO® Xpress Executor provides standalone support for optimization execution services, allowing business to deploy and execute optimization models quickly and easily.  
  3. FICO® Xpress Solver provides the widest breadth of industry leading optimization algorithms and technologies to solve linear, mixed integer and non-linear problems. 
  4. FICO® Xpress Workbench is an Integrated Development Environment (IDE) for developing optimization models, services and complete solutions. FICO® Xpress Workbench is used with and supports all the other FICO Xpress Optimization components.

Key Features

  • Continuous: Simplex LP, Barrier LP, Second Order Conic Programming (SOCP).
  • Mixed Integer/Quadratic:  MIP, QP, MIQP, QCQP, MIQCQP, MISOCP.
  • Nonlinear: SLP for NLP, Interior point methods for NLP and mixed integer versions. 
  • Constraint Programming using the Xpress Kalis option that is based on the Kalis solver from Artelys.
  • Xpress Tuner optimizes parameters for a selected target, such as optimality, gap, etc. and automatically selects and combines settings to achieve best performance.
  • Xpress Solver supports multi-threaded parallel processing out of the box.
  • A unified modelling interface for all solvers is also provided, from linear to general nonlinear, with the accompanying Xpress Workbench.
