New function : pgr maxWeightedMatching - #3139
Conversation
…ode for pgr_maxWeightedMatching
WalkthroughAdds the experimental ChangesMaximum weighted matching
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The new weighted-matching function currently has a dependency gap that can prevent supported builds from compiling, and its example results show agg_cost values that do not match the documented per-edge contract. Release documentation, translations, and generated files also need correction, so the PR is not ready to merge until the build and output issues are fixed. Sequence Diagram(s)sequenceDiagram

clarify instead that the graph is treated as undirected, while preserving the
one-row-per-matched-edge result behavior.

- Around line 42-50: Update the result construction in maxWeightedMatching so
agg_cost preserves each matched pair’s original edge cost. Remove the cumulative
matched_pairs[i].cost rewrite in the relevant driver logic and return each
matched pair unchanged, including the expected weight for pair (3,5).
In `@include/max_flow/maxWeightedMatching.hpp`:
- Line 37: Update the Boost version requirement in CMakeLists.txt to the
earliest version that provides boost/graph/maximum_weighted_matching.hpp, or
replace the include with a compatible implementation for Boost 1.56.0. Ensure
all supported configurations can compile the code using maximum weighted
matching.
In `@pgtap/max_flow/maxWeightedMatching/edge_cases.pg`:
- Around line 36-49: The edge-case tests need a global-weight matching scenario,
not only the triangle’s largest-edge check. Add a graph containing two disjoint
edges whose combined weight exceeds a conflicting edge, assert that both
disjoint edges are returned, and update the surrounding plan(3) count to include
this assertion.

Remove the symmetric-results claim.
Line 51 states that result rows are symmetric. The function returns one row per matched edge, not both (u, v) and (v, u). The exact-set tests in pgtap/max_flow/maxWeightedMatching/edge_cases.pg also require only one orientation. State that the algorithm treats the graph as undirected, or remove this paragraph.

Line 66 uses :issue:3136: without backticks around the number. Every other :issue: reference in this file uses backticks, for example :issue:\3049`and:issue:`3101``. Without backticks, Sphinx does not recognize the role, and the text renders literally instead of linking to the GitHub issue.

Return each matched edge weight in agg_cost. src/max_flow/maxWeightedMatching_driver.cpp:97-102 accumulates matched_pairs[i].cost and overwrites it, so (3,5) returns 11 instead of its edge weight 6. Remove this cumulative rewrite and return each matched pair unchanged.

Add a global-weight optimality case.
The triangle case only verifies the largest single edge. Add a graph where two disjoint edges have a larger combined weight than one conflicting edge. This test must expect both disjoint edges. Update plan(3) to include the new assertion.
