Member Enumeration Documentation

enum Gecode::IntValBranch::Select

Which value selection.

Enumerator:
SEL_MIN 

Select smallest value.

SEL_MED 

Select greatest value not greater than the median.

SEL_MAX 

Select largest value.

SEL_RND 

Select random value.

SEL_SPLIT_MIN 

Select values not greater than mean of smallest and largest value.

SEL_SPLIT_MAX 

Select values greater than mean of smallest and largest value.

SEL_RANGE_MIN 

Select the smallest range of the variable domain if it has several ranges, otherwise select values not greater than mean of smallest and largest value.

SEL_RANGE_MAX 

Select the largest range of the variable domain if it has several ranges, otherwise select values greater than mean of smallest and largest value.

SEL_VAL_COMMIT 

Select value according to user-defined functions.

SEL_VALUES_MIN 

Select all values starting from smallest.

SEL_VALUES_MAX 

Select all values starting from largest.

SEL_NEAR_MIN 

Select value nearest to a given value, use smaller one in case of ties.

SEL_NEAR_MAX 

Select value nearest to a given value, use larger one in case of ties.

SEL_NEAR_INC 

Select value near to a given value, increment values first.

SEL_NEAR_DEC 

Select value near to a given value, decrement values first.
