Detecting or verifying sparsity structure in large scale nonlinear programming (anglais)

This paper describes some algorithms for the following problem : given a nonlinear function defined as a black box, find which variables the function actually depends on (the set of active variables) and for each of these variables test if the relation is linear or nonlinear. Alternatively, verify if a given set of active variables and/or a given linearity pattern is correct. The algorithms are based on group testing and binary search and they are...
