int max_length() const

Return the maximum length.

bool random_segment_in_particle(const Configuration &config, Select *select, Random *random, const int max_length = -1)

  • max_length: Set the maximum length of the segment. If -1 (default), consider all possible lengths.

Select all sites between two randomly selected sites in a randomly selected particle in group. Return true if selection is valid

bool select(const Select &perturbed, System *system, Random *random)
