What this skill does


# DP Optimizer Skill

## Purpose

Apply advanced dynamic programming optimizations to improve time and space complexity of DP solutions.

## Capabilities

- Convex hull trick detection and application
- Divide and conquer optimization
- Knuth optimization
- Monotonic queue/deque optimization
- Alien's trick / WQS binary search
- Rolling array optimization
- Bitmask compression

## Target Processes

- dp-state-optimization
- advanced-dp-techniques
- complexity-optimization

## Optimization Techniques

### Time Optimizations
1. **Convex Hull Trick**: O(n^2) -> O(n log n) for certain recurrences
2. **Divide & Conquer**: O(n^2 k) -> O(n k log n) when optimal j is monotonic
3. **Knuth Optimization**: O(n^3) -> O(n^2) for certain interval DP
4. **Monotonic Queue**: O(n*k) -> O(n) for sliding window DP

### Space Optimizations
1. **Rolling Array**: O(n*m) -> O(m) when only previous row needed
2. **Bitmask Compression**: Reduce state space with bit manipulation

let-fate-decide

Included

Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
