A general condition determining the optimal performance of a complex system has not yet been found and the possibility of its existence is unknown. To contribute in this direction, an optimization algorithm as a complex system is presented. The performance of the algorithm for any problem is controlled as a convex function with a single optimum.

Details of the analysis of the ηπ − system studied in the reaction π − p → ηπ − p at 18 GeV/c are given. Separate analyses for the 2γ and π + π − π 0 decay modes of the η are presented. An amplitude analysis of the data indicates the presence of interference between the a − 2 (1320) and a J P C = 1 −+ wave between 1.2 and 1.6 GeV/c 2. The phase difference(More)
