An Unconstrained Optimization Test Functions Collection

Abstract. A collection of unconstrained optimization test functions is presented. The purpose of this collection is to give to the optimization community a large number of general test functions to be used in testing the unconstrained optimization algorithms and comparisons studies. For each function we give its algebraic expression and the standard initial point. Some of the test fnctions are from the CUTE collection established by Bongartz, Conn, Gould and Toint, [1995], others are from Moré, Garbow and Hillstrom, [1981], Himmelblau [1972] or from some other papers or technical reports.
