The genesis of the UTILIB library is in the BBUMS library developed by Bill Hart and Brian Bartell while graduate students at U.C. San Diego. Although Brian would probably not recognize any othe the UTILIB software, the design of some of the most widely used software, like array classes, is due to him. The BBUMS library was subsequently reorganized and renamed the SGOPT library, which focuses on a methods for global optimization. UTILIB was the stdlib subdirectory in SGOPT, which was extracted from SGOPT when it became clear that several groups at Sandia would be interested in using the UTILIB components without the additional baggage of the optimizers in SGOPT.
I would like to thank Cindy Phillips, Jonathan Eckstein and Mike Eldred for their input on this software. Each of them has identified numerous bugs, and refinements in the configuration process are largely due to the demands that their uses of UTILIB have made.
The UTILIB library includes several files taken from the RANLIB.C library of C routines for random number generation, which was developed by Barry W. Brown and James Lovato, Dept of Biomathematics at the University of Texas, Houston.
