+/**
+ * Production-ready Incremental K-Core algorithm implementation.
+ *
+ * <p>This implementation provides comprehensive K-Core computation for
dynamic graphs with:
+ * - Efficient incremental updates for edge additions/deletions
+ * - Proper state management for distributed computation
+ * - Change detection and status tracking (INIT, UNCHANGED, ADDED, REMOVED)
+ * - Convergence detection and early termination
+ * - Memory-efficient vertex-centric computation model
+ * - Production-level error handling and logging
+ *
+ * <p>Algorithm Overview:
+ * K-Core is a maximal subgraph where each vertex has at least k neighbors
within the subgraph.
+ * The algorithm iteratively removes vertices with degree < k until
convergence.
+ *
+ * <p>Incremental Processing:
+ * - Tracks vertex states across multiple iterations
+ * - Efficiently handles graph updates by maintaining change status
+ * - Supports both static and dynamic graph scenarios
+ *
