 A Sobol sequence is a low discrepancy quasi-random sequence. Sobol sequences were designed to cover the unit 
-hypercube with lower discrepancy than completely random sampling (e.g. |random-search|). Optunity supports Sobol
+hypercube with lower discrepancy than completely random sampling (e.g. |randomsearch|). Optunity supports Sobol
 sequences in up to 40 dimensions (e.g. 40 hyperparameters). 
 
 The figures below show the differences between a Sobol sequence and sampling uniformly at random.
