Placer Deposit: From Modeling to Evaluation
2013The report is devoted to methodology of prognostic-search model construction of ore placer deposit on the basis of its multifactor multitag models under study by logic-informational methods. The logic-informational model is represented by feature set, informative for solution of prognostic problem. All informative tags receive a quantitative estimation
