Optimizer .NET Library Reference

Covered Topics

• Introduction
  The best way to get started using the wrapper is to open up the example projects included with this package and experiment with them.
• Using the Wrapper in Projects
  The Optimizer functionality is exposed through the XPRS and XPRSprob classes, which reside in the Optimizer namespace, which resides in the xprsdn.dll assembly.
• Using the Interface
  The .NET wrapper for the Xpress Optimizer has been designed to look and feel like the Common Language Runtime.
• Controls and Attributes
  The Optimizer controls and attributes are properties of the XPRSprob object.
• Callbacks
  The Optimizer callbacks are accessed using the .NET event / delegate mechanism.
• Return Codes and Error Checking
  Most of the functions in the C interface to the Optimizer use an integer return code to indicate if an error occurred.
• Destroying the Problem
  Since .NET uses a garbage collector, it does not provide a mechanism for explicitly destroying objects.
• Branch Bounds
  Another notable change with the .NET interface is to the functions used to store and set the bounds for node separation during a global search.
