To run them, use:\n\n    python run.py data/measures-262-1-34823-45550.csv\n\nYou should see a table comparing results from using the original method with and\nwithout weighting, and with and without running RANSAC before the actual\noptimization.\n\npadnums.py is an adapted version of the found module at [this blog post][link-padnums]\n\nDependencies: scipy and numpy.\n\n[ransac-repository]: https://github.com/FredrikAppelros/ransac\n[ransac-wikipedia]: https://en.wikipedia.org/wiki/RANSAC\n[link-stackexchange]: http://gis.stackexchange.com/questions/40660/trilateration-algorithm-for-n-amount-of-points?lq=1\n[link-padnums]: http://ginstrom.com/scribbles/2007/09/04/pretty-printing-a-table-in-python/\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Feggpi%2Fichnaea-experiments","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Feggpi%2Fichnaea-experiments","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Feggpi%2Fichnaea-experiments/lists"}
