# Contrasting Two Transformation-Based Methods for Obtaining Absolute Extrema

## TL;DR

This paper compares two direct transformation-based methods for finding absolute extrema and extremizers, highlighting their differences from variation-based approaches and emphasizing their inspection-based solution process.

## Contribution

It provides a comparative analysis of Carlson and Leitmann's method and Silva and Torres's method for obtaining absolute extrema directly.

## Key findings

- Both methods allow direct solution by inspection.
- They differ from traditional variation-based methods.
- The paper clarifies the applicability of each method.

## 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.
