This development contains formalizations and correctness proofs, using Coq and the Mathematical
Components library, of algorithms originally due to Kosaraju and Tarjan for finding strongly
connected components in finite graphs. It also contains a verified implementation of topological
sorting with extended guarantees for acyclic graphs."""

Dry install 🏜️

Dry install with the current Coq version:

Command
opam install -y --show-action coq-mathcomp-tarjan.1.0.2 coq.8.5.1
Return code
5120
Output
[NOTE] Package coq is already installed (current version is 8.5.1).
The following dependencies couldn't be met:
  - coq-mathcomp-tarjan -> coq >= 8.16 -> ocaml >= 4.09.0
      base of this switch (use `--unlock-base' to force)
  - coq-mathcomp-tarjan -> coq >= 8.16 -> coq-core -> ocaml >= 4.09.0
      base of this switch (use `--unlock-base' to force)
No solution found, exiting

Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:

Command
opam remove -y coq; opam install -y --show-action --unlock-base coq-mathcomp-tarjan.1.0.2
