maxkcut

Generic Description

A partitioning procedure that aims to maximize the weight of edges cut between groups.

Simple example:

CALL nexyron.maxkcut()

Community detection procedures partition or group nodes by structural affinity. They are useful for segmentation, fraud-ring analysis, recommendation features, and exploratory graph profiling.

Consumer-Level Explanation

Use max-k-cut when you want to split the graph so strong interactions end up across groups, usually for balancing, testing, or separation objectives. Different community algorithms optimize different objectives and assumptions. Modularity methods, label propagation, block models, overlapping memberships, and partition-quality metrics should be chosen for the question, not swapped blindly.

Conceptual Explanation

Max-k-cut is again not a community detector in the “find internally cohesive groups” sense. It deliberately prefers splits that sever strong cross-group interaction. That can be exactly what you want in balancing, partition planning, adversarial separation, or experiment design.

How It Differs From Nearby Algorithms

Compared with community algorithms, it often pushes the graph apart rather than grouping dense neighborhoods together. Compared with coloring, it optimizes cut quality rather than just conflict legality. Compared with conductance, it is an optimization target rather than a validation score.

When To Choose It

More Detailed Explanation

This is useful when the business question is “how should we divide this?” rather than “what communities already exist?” That distinction matters a lot in documentation and user education

In practical queries, start by deciding the row grain you want after the call: one row per node, one row per path, one row per registry object, one row per artifact, or one row per summary. Then keep that grain explicit with YIELD and named projections. That is the difference between a useful planner-facing example and a vague call that downstream tooling cannot safely compose. For contract-driven procedures, the executable examples on these pages intentionally inspect procedure metadata unless the required named artifacts are created in the same example.

Advanced Example

The advanced example keeps maxkcut in a named Cypher pipeline so the procedure output shape, downstream filters, and returned columns are visible to planner tooling.

CALL nexyron.maxkcut() YIELD node_id, partition_id, cut_weight
RETURN node_id, partition_id, cut_weight
LIMIT 10
