Noting two syntypes of hoplomystax with 1 instead of 2 midventral scales posterior to the origin of the pelvics, and the unusual color of S. abbotti, Dr. Bohlke kindly sent these fishes on loan.

For this problem, the simulated annealing-based heuristic provides a near-optimal solution.

The score was 30 all when the rain delay started.

Tawarmalani and Sahinidis (2001) developed the convex envelope and concave envelope for x/y over a unit hypercube, compared it to the convex relaxation proposed by Zamora and Grosmmann (1998a), (1998b), (1999), proposed a semidefinite relaxation of x/y, and suggested convex envelopes for functions of the form f(x)y² and f(x)/y.
