Chapter 22 — Single-Source Shortest Paths

This is the canonical CLRS fourth-edition chapter guide during the migration period.

Current source

Sections 22.1--22.5 are native fourth-edition sections (Bellman–Ford, SSSP in DAGs, Dijkstra, difference constraints, and the shortest-path property proofs), imported directly from Section 22.1, Section 22.2, Section 22.3, Section 22.4, and Section 22.5. Declarations retain the legacy CLRS.Chapter24 namespace during the compatibility period; the third-edition-numbered imports CLRSLean.Chapter_24 and CLRSLean.Chapter_24.Section_24_* forward to these sources.

Coverage boundary

The native sections supply the represented fourth-edition single-source-shortest-path sections: Bellman-Ford (Theorem 22.4, with the O(V·E) work bound), SSSP in DAGs, Dijkstra, difference constraints (Theorem 22.9), and the full §22.5 shortest-path-property stack (Lemmas 22.10--22.16, including the subpath, convergence, path-relaxation, and predecessor-subgraph properties).

See docs/clrs-fourth-edition-map.csv for the section-level mapping and docs/migrations/clrs4.md for compatibility and deprecation policy.
