In this work, the concentration gradient (CG) analysis of local-scale exploration for Porphyry-Cu deposits is applied in two zones using the G(Vz) index (CG(Zn*Pb)/CG(Cu*Mo)). The first zone is covered by a 1:2000 map of the Sungun and Astamal areas in NW Iran and the second one in the Inza area in British Columbia, Canada. The rock samples are taken from Sungun and Astamal and the soil samples...

We use GRASP strategies to solve the problem of selecting financial ratios to model and predict business failure. As a previous step, we use the GRASP procedure to select a subset of financial ratios that are then used to estimate a model of logistic regression to anticipate finanical distress on a sample of Spanish firms. The algorithm we suggest is designed “ad-hoc” for this type of variables...
