Article: Lasers reveal Maya war ruins

“ARCHAEOLOGISTS GUIDED BY laser images of a remote region of northern Guatemala have discovered 20-foot-high walls, watchtowers, and other evidence that ancient Maya societies waged large-scale warfare over many years. The finds have upended long-established impressions of a civilization that tamed the jungle and built thriving cities, then declined and disappeared beneath the dense tropical forest.”

The archaeologists used a unique “systemic process of trial and error” in this real-life example. It is clear though that archaeological discoveries do not “always” use such a process.
