The Test Set

The set of test problems is the same as that in [5]. Five problems were taken from [3]. They were selected to be non-trivial problems with a variety of constraint types, as well as differing numbers of variables, inequality constraints, equality constraints and bound constraints. The remaining three problems were taken from [8]. They are relatively simpler. Each problem is identified with a mnemonic, given below.

fphe1

is the first heat exchanger network test problem in [3, pages 63-66,].

fpnlp3

is the third nonlinear programming test problem in [3, page 30,].

fpnlp6

is the sixth nonlinear programming test problem in [3, page 30,].

fppb1

is the first pooling-blending test problem in [3, page 59,].

fpqp3

is the third quadratic programming test problem in [3, pages 8-9,].

gould

is the first test problem in [8].

bracken

is the second test problem in [8].

wolfe3

is the third test problem in [8].
