Detailed Description

The default rule for categorizing constraints into those that are strictly satisified and those that are not.

The rule divides the constraints into 5 categories

• equality constraints
• lower bounds that are strictly satisfied;
• upper bounds that are strictly satisfied;
• lower bounds that are not strictly satisfied; and
• upper bounds that are not strictly satisfied.

The default criterion for accepting a lower bound as strictly satisfied is

where u is taken to be infinite if there is no upper bound. The rule for an upper bound to be strictly feasible is analogous.

Constructor & Destructor Documentation

DefaultCategorizeGenConstraints::DefaultCategorizeGenConstraints (  double    rtol, double    atol, double    bignum )  [inline]

Constructor. Parameters: rtol  the relative tolerance for accepting a constraint as strictly satisfied. atol  the relative tolerance for accepting a constraint as strictly satisfied. bignum  a value beyond which a bound is taken to be infinite.

Member Function Documentation

virtual void DefaultCategorizeGenConstraints::operator() (  unsigned char    result[], int    len, int    ncat, const double    rclow[], const double *    rhs[], int    nrhs )  const [virtual]

Classify the constraints. Parameters: result  a vector of clasifications len  the length of result and all double arrays ncat  the number of categories (will always be 5) rclow  the lower bounds rhs  [0] the function values, c rhs  [1] the upper bounds nrhs  the number of right hand sides (will always be 2) Implements IotrVectorCategorize.
