Problem

Given a directed graph with weighted nodes, find the a set of cycles that don't share any nodes, maximizing the total sum of the node weights. Ties can be broken arbitrarily.

Example 1

All nodes have weight 1

Context

There exists a Color space.

weight(Color) = real number between 0 and 1 

difference(Color, Color) = real number between 0 and 100

Abstract

Create a "as-a-library" implementation of Bash, offering live-inspection capabilities.

Capabilities

• Run any batch script as normal
• Ask for a semantic bound-tree of an arbitrary expression
• Ask for a lint in a specific environment (detect undefined env-vars)
• Debug shell script
