Wed Aug 20 23:17:38 EDT 1997 hs87.mod: correct the data-section value for param b (to accord with Himmelblau, rather than Hock & Schittkowski), and add comments about modifying the objective to make it continuous. Mon Oct 20 16:45:16 EDT 1997 hs105.mod: correct upper bound on x[2], which should be .499 rather than .449. Tue Dec 15 19:35:15 EST 1998 hs106.mod: correct upper bound on x[1], which should be 10000 rather than 1000. Sun Dec 20 14:53:58 EST 1998 steenbre.mod: in the data section, add a := to the "var capacity" line, for the benefit of older AMPL processors (prior to 19960819).
