Agent Skills: Flow Network Builder Skill

Flow Network Builder Skill

Purpose

Model optimization problems as network flow problems, constructing appropriate flow networks and selecting optimal algorithms.

Capabilities

• Identify max-flow/min-cut modeling opportunities
• Construct flow network from problem description
• Select optimal flow algorithm
• Handle min-cost flow variants
• Bipartite matching reduction
• Circulation problems

Target Processes

• advanced-graph-algorithms
• graph-modeling
• optimization problems

Flow Problem Types

1. Maximum Flow: Find max flow from source to sink
2. Minimum Cut: Partition minimizing cut capacity
3. Bipartite Matching: Maximum matching via flow
4. Min-Cost Max-Flow: Cheapest maximum flow
5. Circulation: Flow with lower bounds

Reduction Patterns

• Assignment problems -> Bipartite matching
• Scheduling -> Flow with constraints
• Path cover -> Flow reduction
• Edge-disjoint paths -> Unit capacity flow
