Detailed Description

template<class PERM>
class permlib::SetwiseStabilizerPredicate< PERM >

predicate for the subgroup that stabilizes a given point set

Constructor & Destructor Documentation

◆ SetwiseStabilizerPredicate()

template<class PERM>
template<class InputIterator>
permlib::SetwiseStabilizerPredicate< PERM >::SetwiseStabilizerPredicate ( InputIterator begin,
InputIterator end )

constructor

Parameters
beginbegin iterator for list of points (unsigned long) to be stabilized
endend iterator for list of points (unsigned long) to be stabilized

Member Function Documentation

◆ childRestriction()

template<class PERM>
bool permlib::SetwiseStabilizerPredicate< PERM >::childRestriction ( const PERM & h,
unsigned int i,
unsigned long beta_i ) const
virtual

checks if a given group element should not be followed in backtrack search

If returns false then element h that arises at backtrack level i with corresponding base element beta_i will not extend to a "complete" group element that fulfills the predicate

Parameters
h(partial) group element, arising in the backtrack search
ibacktrack recursion level
beta_ibase element corresponding to current backtrack recursion level

Implements permlib::SubgroupPredicate< PERM >.

◆ limit()

template<class PERM>
unsigned int permlib::SetwiseStabilizerPredicate< PERM >::limit ( ) const
virtual

limit of recursion depth in backtrack search

only images of the #{limit()} first base points have to be considered

Implements permlib::SubgroupPredicate< PERM >.

◆ operator()()

template<class PERM>
bool permlib::SetwiseStabilizerPredicate< PERM >::operator() ( const PERM & ) const
virtual

true iff group element fulfills predicate

Implements permlib::SubgroupPredicate< PERM >.
