title: A novel algorithm to optimize classification trees

description: Abstract Breiman et al. (1984) expounded a method called Classification and Regression Trees, or CART, which is of use for nonparametric discrimination and regression. In this paper we present an algorithm which is able to increase the quality of classification trees beyond the quality of trees, which are based on direct evaluation of a splitting criterion. The novel algorithm calculates a large number of possible segments of trees instead of a single tree, and recursively selects the best of these pa... Title of program: MedTree 3.1 Catalogue Id: ADCY_v1_0 Nature of problem The problem is to find best trees of classification for a specific subject to one of two groups [1]. Initially, a set of features for a (sufficient) large number of representative subjects from both groups must be sampled by the user. A good tree is expected to be found if there exist simple schemes of behaviour, or even complex correlations within the input information. The algorithm allows to take into account boundary conditions, to fit the practical purpose of the classification tree.

title: A Monte Carlo program to generate mini-jet events in the two-photon process

description: Abstract An event generator for resolved photon processes in photon-photon collisions in e^+ e^-reactions has been developed. The program can generate direct, once-resolved and twice-resolved processes either separately or simultaneously according to user switches. Title of program: MINIJET Catalogue Id: ADDF_v1_0 Nature of problem In high energy two-photon processes in e+e- reactions, the hadronic components of the photon contribute significantly to the process. In particular, jet production in (almost real) photon-photon collisions offers an opportunity to test perturbative QCD. In addition, the understanding of the process is indispensable for designing future high energy e+e- linear colliders.
