search_frozen_geodesicR Documentation

A pseudo-derivative, line search algorithm along frozen geodesics.

Description

A pseudo-derivative, line search algorithm along frozen geodesics.

Usage

search_frozen_geodesic(
  current,
  index,
  tries,
  max.tries = 5,
  n = 5,
  frozen,
  cur_index = NA,
  ...
)

Arguments

current

starting projection

index

index function

tries

the counter of the outer loop of the opotimiser

max.tries

maximum number of iteration before giving up

n

number of random steps to take to find best direction

frozen

a matrix of frozen variables

cur_index

the index value of the current basis

...

other arguments being passed into the search_frozen_geodesic() 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.

To do

eliminate these functions
