Linear Programming and Optimization

Company: ILOG

"ILOG is a leading provider of advanced C, C++ and Java software components for graphics and resource optimization. ILOG products and CPLEX, its linear optimization division, deliver high-performance data visualization for 2D and 3D user interfaces; integer, linear and constraint solvers for resource optimization, scheduling, logistics and planning applications; dynamic rule systems for intelligent agents and real time data flow control, and components for integrating modules with real time and relational data sources."

Capabilities/techniques:

The ILOG Optimization Suite has two core engines:
ILOG Solver "constraint programming for resource allocation"

ILOG Planner "the Simplex based cooperating solver"

"Used by leading companies such as Michelin, Fygir logistic information systems, Air France, France Telecom and Eurocontrol, ILOG Planner has long been an ideal choice for production and procurement planning, staff scheduling and satellite mission planning. ILOG Planner 2.2 adds the power of linear programming to constraint programming, which is well known for its modeling and search control capabilities."

Product(s): Optimization Subroutine Library (OSL)

Capabilities/techniques:

"OSL is IBM's library of high-performance optimization subroutines for linear, mixed integer and quadratic programming, supported on multiple hardware platforms, from PCs, to workstations, to supercomputers such as the SP2."
 

Product(s):

"Frontline Systems Inc. is the spreadsheet solver company. We created the Solver in Microsoft Excel, the new Solver in Lotus 1-2-3 97, and the Optimizer in Corel Quattro Pro. We market enhanced versions of these spreadsheet solvers which offer greater capacity, much greater speed, and many new ease-of-use features. We also offer solvers callable from Visual Basic, C/C++ and other languages, and solvers for the AMPL and AMPL Plus modeling systems."
