Indirect Methods for Optimal Control
2017In this chapter, indirect methods to solve optimal control problems are discussed. Indirect methods rely on first-order necessary conditions, summarized in Pontryagin’s minimum principle, and attempt to locate control and state trajectories, which satisfy these conditions.

Indirect methods to estimate hidden population.
Revista espanola de salud publica, 2018Estimating the prevalence of the so-called “hidden populations” can be challenging, because the identification of its members is difficult due to their socially sanctionable or illegal behaviours. This article provides a critical review of the most widely used methods for estimating the size of a hard-to-reach population.

Since the number of images on one plate can exceed a million, methods which involve counting the stars individually are obviously very limited in scope.
