Abstract: The current subject matter relates to generation, modification, export, and/or import of decision trees, based on which optimal treatments (for example, offers) can be assigned to various records (for example, customers). A tree-generating application can receive constraints characterizing specifications for a decision tree desired by the user of the tree-generating application. The tree-generating application can generate a mathematical equation based on the constraints. The tree-generating application can receive, from a first database, historical data characterizing treatments provided to a plurality of representative customers having corresponding attributes. The tree-generating application can execute a simplex method of linear programming to search for the decision tree desired by the user from a plurality of decision trees stored in a second database stored in a second database. The tree-generating application can send the decision tree to a tree-using application.
