Detailed Description

Error handling in libDAI is done by throwing an instance of the Exception class.

The Exception class inherits from std::runtime_error. It defines several types of exceptions and corresponding error messages. The recommended way to throw an instance of the Exception class is by using the #DAI_THROW or DAI_THROWE macros.

Examples:: example.cpp, and uai2010-aie-solver.cpp.
