Study Notes
Graph Terminology
- Graphs represent pairwise relationships among objects
- A graph G consists of nodes (V) and edges (E)
- Each edge joins two nodes
- An edge is represented as a two-element subset of nodes (e = {u, v})
- Graphs are depicted with nodes as circles and edges as connecting lines
Interval Scheduling Problem
- A scheduling problem for maximizing resource usage
- Each request (i) has a start time (si) and finish time (fi) (si < fi)
- Compatible requests do not overlap in time (either fi ≤ sj or fj ≤ si)
- A subset of requests is compatible if all pairs within the subset are compatible
PSPACE-Complete Problems
- Problems in game-playing and planning
- Believed to be harder than NP-complete problems
- Characterized by a lack of short "proofs" for solutions
Stable Matching Problem
- Involves n men and n women with preference lists
- Some individuals are classified as "good"
- Each preference list ranks good people (opposite gender) higher than bad people
- All good men are married to good women in every stable matching.
Data Structures and Algorithm Design
- Data structures are introduced as needed
- Chapters 4-7 cover algorithm design techniques:
- Greedy algorithms
- Divide and conquer
- Dynamic programming
- Network Flow
