Contrasting Two Transformation-Based Methods for Obtaining Absolute Extrema
arXiv:0704.0473 · doi:10.1007/s10957-007-9292-z
Abstract
In this note we contrast two transformation-based methods to deduce absolute extrema and the corresponding extremizers. Unlike variation-based methods, the transformation-based ones of Carlson and Leitmann and the recent one of Silva and Torres are direct in that they permit obtaining solutions by inspection.
