How to prove the local search algorithm can find the maximum weight independent set in a mat...
I am trying to prove a simple local search algorithm could solve exactly this problem:
$\underset{S \in I(M), |S|=k}{max} c(S)$
where $M$ is a matroid, and $ I(M)$ is the set of all independent set, …

Optimization over permutation
The Problem
This is the problem I am working on: Given a set $X = \{x_1, x_2, \cdots , x_n\}$ in a metric space, find an optimal ordering $\pi : X \rightarrow X$ that maximizes the following objective …
