Condensed Information on the Test Problems

Abstract

To give a first survey of the test examples and their solution properties, a comprehensive list of all problems is presented in Table 1. Besides the current problem number and the classification number OCD-Kr-s as described in Chapter I, we report the dimension n, the number of all inequality constraints m₁, the number of all equality constraints m-m₁, and the number of all bounds b. If linear restrictions exist, their number is given in the brackets behind m₁ or m-m₁, respectively. The column headed by x_o gives the information, whether the starting point x_o is feasible (T) or not (F). Moreover, the objective function value f(x*) is displayed, where x* denotes either the exact solution, if known in advance, or a solution computed numerically by the nonlinear programming code NLPQL. Any numerical data not given in full length, are assumed to be exact, i.e. the remaining digits are zero.
