Web21 apr. 2024 · During a Life Cycle Assessment (LCA), environmental impacts are evaluated throughout the entire life cycle of a product (production, use and disposal or recovery). This also includes the upstream and downstream processes associated with production (e.g., the production of raw, auxiliary and operating materials) and with the product’s final ... WebOverview. Lowest common ancestor (LCA) of two nodes x x and y y in a tree or directed acyclic graph (DAG) is the deepest (lowest) node that has both x x and y y as descendants. Hence, LCA is the ancestor of x and y which is the farthest from the root node in a tree. In most cases, we also consider a node to be a descendant of itself.
