Part 7/10:
To achieve this minimized space calculation, Williams embarked on a dual-step process of mapping the computation and recombining its segments into a coherent output. At its heart lies the concept of causal relationships along a computational timeline, akin to tracing back through a timeline to understand dependencies for recreating results.
This refreshing approach drew parallels with a "pebbling game," an intriguing exercise where players strategically move pebbles to a root node on a tree-like structure, reusing pebbles efficiently to rank the least resource-consuming methods of achieving a target.
