sts_seed_search VS SeedSearch

I checked the maps for paths that avoid all unnecessary combats so that each map only encounters a combat at the start and bosses. Empirically, this occurs 1 in 833 runs on non-Ascension mode and 1 in 1100 in Ascension mode per map, so roughly 1 in a half billion seeds meets this constraint. I used the C++ StS seed search for this filter. For later searches, I'd like to port the map node assignment code to CUDA for better filtering, but it's hard to debug :'(

Gamerpuppy's project is MUCH MUCH faster than this but isn't built into the game, so check that out if you're interested in finding seeds in a different but faster way. ForgottenArbiter's project will find more specific paths to find a seed that you want and it will tell you the path you should take for your chosen criteria and you can be much more specific with your filters.

seed searching: a C++ codebase which has basically everything in the game implemented

How? (1) labbing out how bypass combats without spending stacks of Neow's Lament, (2) programming a specialized seed search based off of GamerPuppy's code, (3) routing and manipulating the RNG, (4) executing the route.

Not exactly a tool yet, but some code I wrote here https://github.com/gamerpuppy/sts_seed_search

I know of something that goes in the opposite direction -- looks for a seed that matches certain conditions, instead of what you want (looks up conditions that are true for a specific seed). So, it should be theoretically possible, at least?

Finally, I used Arbiter's SeedSearch mod to eyeball the routes to check for potions, card rewards, etc.

most seeds are found randomly yes, there's a document with a bunch of pandora box swaps (on PC) but if that's not what you're asking there are things like https://github.com/ForgottenArbiter/SeedSearch

You could feed the seed into Seedsearch to see what the last boss is. Just configure it to not search for anything in particular. Or you could use Achievment enabler to enable them even when using a seeded or modded run.

You could always try Seed Search to find a run with a sufficiently strong start. It probably is easier than you think, with access to infinites, buffer stacks, intangibility, etc.
