Hierarchical methods refer to a class of algorithms that build clusters step by step, either by merging smaller clusters into larger ones (agglomerative approach) or by splitting larger clusters into smaller ones (divisive approach). "Optimizing partitioning" and "parallel threshold" are not hierarchical methods; instead, they relate to different clustering strategies. "Variance" can be a part of hierarchical clustering methods, especially in variance-based clustering like Ward's method, which minimizes the variance when forming clusters.
