https://en.wikipedia.org/wiki/Sobol_sequence Used to gridsearch efficiently without getting fancy.

exp clj

(exp item-range)

Exponential exploration of the space.

gridsearch clj

(gridsearch option-map & [gridsearch-start-index])

Given an option map return an infinite sequence of maps. Values in the map that are fn? are considered valid options for the gridsearch.

linear clj

(linear item-range)

Linear search through the area.

make-gridsearch-fn clj

(make-gridsearch-fn target-range grid-fn)

map->path-value-seq clj

(map->path-value-seq data-map)

Given a map, return a path-value seq where each path is the sequence of keys to get the value.

nominative clj

(nominative label-vec)

Non-numeric data. Vector of options.

path-item-seq->map clj

(path-item-seq->map path-item-seq)

sobol-seq clj

(sobol-seq n-dims gridsearch-start-index)

Given a dimension count and optional start index, return an infinite sequence of points in the unit hypercube with coordinates in range [0-1]. :start-index - starting index. Constant time to start at any index. Returns sequence of double arrays of length n-dim.
