search_frozen_geodesic: Search for most interesting projection along frozen geodesics.
Description
These three functions perform a corresponding role to
search_geodesic, find_best_dir and
find_path_peak but for the frozen tour. They work by
zero'ing out the frozen variables and travelling in that restricted
subspace.
Usage
search_frozen_geodesic(current, index, max.tries = 5, n = 5, frozen)
To do
eliminate these functions
