Description (last modified by Víctor de Buen Remiro)

Es necesario contar con un sistema de optimización con restricciones de desigualdad lineal sparse.

\min f\left(x\right)

Sujeto a

A x \ge a

x\in\mathbb{R}^{n}

a\in\mathbb{R}^{r}

A\in\mathbb{R}^{r\times n}

Concretamente es necesario resolver problemas de programación cuadrática

\min x^T C x + c^T x

Sujeto a

A x \ge a

y en particular el problema de mínimos residuos

\min e^T e

Sujeto a

e = y - B x

A x \ge a

B\in\mathbb{R}^{m \times n}

y\in\mathbb{R}^{m }

El principal motivo es dar un punto inicial interior en la simulación de modelos bayesianos en general y de BSR en particular.
