Convergence of the Non-Uniform Directed Physarum Model

Enrico Facca, Andreas Karrenbauer, Pavel Kolev +1

The directed Physarum dynamics is known to solve positive linear programs: minimize $c^{T} x$ subject to $A x = b$ and $x \geq 0$ for a positive cost vector $c$ . The directed Physarum…

Convergence of the Non-Uniform Physarum Dynamics

Andreas Karrenbauer, Pavel Kolev, Kurt Mehlhorn

Let $c \in Z_{> 0}^{m}$ , $A \in Z^{n \times m}$ , and $b \in Z^{n}$ . We show under fairly general conditions that the non-uniform Physarum dynamics \[ \dot{x}_…
