Struct DynamicCutWatcher

Source

pub struct DynamicCutWatcher { /* private fields */ }

Expand description

Dynamic cut watcher using incremental min-cut updates

Tracks the minimum cut value of the graph and identifies weak boundaries. Uses Stoer-Wagner for global min-cut and incremental updates for efficiency.
