Usage

search_better(
  current,
  alpha = 0.5,
  index,
  tries,
  max.tries = Inf,
  ...,
  method = "linear",
  cur_index = NA
)

Arguments

current	starting projection
alpha	the angle used to search the target basis from the current basis
index	index function
tries	the counter of the outer loop of the opotimiser
max.tries	maximum number of iteration before giving up
...	other arguments being passed into the search_better()
method	whether the nearby bases are found by a linear/ geodesic formulation
