Notes. From left to right, we give: the parameters used for running the Locally Aligned Ant Technique (LAAT), the values used for each parameter, and its definition. Note that we give the advisable range for the neighborhood radius parameter r for this specific work. In the second part of the table we give: the index of the three runs, the value of r used for each run, the number of stars in the input dataset, Ni, the number of stars remaining after the filtration based on the pheromone, Nf, and the time needed for each LAAT run using the unparallelized MATLAB implementation of LAAT on a machine with a 1.8 GHz × 8 processor and 15.3 GiB of RAM memory.
