Here’s a randomly generated cipher of unknown type.
The random forest ID test put the correct type in eighth place. The Bion’s Gadgets neural net test didn’t mention the correct type. My experimental neural net ID test put the correct type in first place and no other types were listed, so I tried its type first and solved it. A hill-climber got a practical solution without a crib. A key-search program also got the solution without a crib. I’ll include a caesar-shifted crib.
