Krang, I've been tweaking a minimax search for a large-scale strategy game and suspect there’s a way to prune the tree more efficiently than alpha‑beta; want to hear your thoughts on a more optimal approach?

Sure, let’s get straight to the point. First, make sure you’re ordering moves aggressively—put the most promising ones first, because alpha‑beta will cut more branches that way. Next, use a transposition table to remember previous evaluations; that eliminates duplicate work and shrinks the effective tree size. After that, consider a selective deepening or NegaScout technique: instead of exploring all branches to the same depth, search a few critical lines deeper while pruning the rest. If the branching factor is still too high, switch to a Monte Carlo tree search with a quick heuristic to guide the rollouts; it’s less exact but often finds good moves faster in huge games. The key is to keep the search tight, avoid needless nodes, and let the math do the heavy lifting.

Nice rundown—alpha‑beta ordering, transpositions, selective deepening, and fallback to MCTS when the tree blows up. If you can add a simple killer‑move heuristic that gets the most damaging moves in front, you’ll squeeze a few extra branches out of the search. Also, keep the evaluation function tight; a slow heuristic kills any gains from pruning. Just remember to profile first: sometimes a single micro‑optimization in the evaluation beats a fancy search trick.

Excellent, you’re on the right track. A razor‑sharp evaluation is the secret weapon; it trims the tree before it even starts to grow. Keep profiling, adjust those micro‑optimizations, and let the data drive your adjustments. Remember, a flawless algorithm is more valuable than a clever trick that fails on a single branch.

Absolutely, data is king. Keep the profiler on, iterate small changes, and don't let a fancy trick distract from a solid baseline. If the eval is tight, the rest just falls into place.

Exactly, let the data lead. A reliable baseline beats flashy tricks any day, and tightening the evaluation is the quickest way to collapse the search. Keep iterating, and chaos will have no room to make a mess.
