SOPT is an efficient optimizer for linear, integer, and nonlinear programs. It offers a variety of new and fast algorithms and application capabilities for industrial decision support systems. Based on breakthrough technologies in math programming, SOPT solves problems with lightning speed and robustness.

Highlights

Currently SOPT has three versions, SOPT-CP for linear and nonlienar programs, SOPT-IP for linear and integer programs, and SOPT-SP (SOPT-IP and AMPL). Each module has practical implementation of unique algorithms, which may help your solution development to solve complex decision problems.

Supported Plaforms:

SOPT can be used stand-alone, or as a subroutine library or DLL.

Latest version of SOPT

A new version SOPT 4.2 will be released on August 25. With theis release, SOPT creates a dynamic optimization log with information on incumbent solution values and elasped times so that users can access the ongoing optmization status even when SOPT is still solving the problem. This feature is particularly useful for online applications such as SaaS appliacations.

Recent releases include such features as retrieval of multiple integer solutions from the SOPT data structure, and various solutions files in the CSV format. Choosing one of multiple near-optiomal solutions is a practical and convenicent way to identify the best solution for your application, when the best objective value may not mean the best solution. Recent release note for SOPT is available from here SOPT Release Note.

Previously we introduced a new search algorithm in version 3. This extended search algorithm uses cutting planes and sub LP solutions, and it tries to find better integer solutions by moving away from local optima. It has been applied to difficult combinatorial problems, such as set covering and TSP problems, which are often found in scheduling and routing applications. The last version also included GUI improvement such as displaying LP and IP solution performance.
