# DP State Designer Skill

## Purpose

Assist in designing optimal dynamic programming states, transitions, and optimizations for complex DP problems.

## Capabilities

- Identify subproblem structure from problem description
- Suggest state representations (dimensions, parameters)
- Derive transition formulas
- Identify optimization opportunities (rolling array, bitmask compression)
- Generate state space complexity estimates
- Detect overlapping subproblems

## Target Processes

- dp-pattern-matching
- dp-state-optimization
- dp-transition-derivation
- advanced-dp-techniques

## DP Design Framework

1. **Subproblem Identification**: What smaller problems compose the solution?
2. **State Definition**: What parameters uniquely identify a subproblem?
3. **Transition Formula**: How do we combine subproblem solutions?
4. **Base Cases**: What are the trivial subproblems?
5. **Computation Order**: In what order should we solve subproblems?
6. **Space Optimization**: Can we reduce memory usage?
