A deterministic algorithm that trades time for memory. Repos like BSGS-CUDA run on GPUs. For a 256-bit key, BSGS would require storing 2^128 "baby steps" (that's 10^38 entries). That is more storage space than exists on all the hard drives on Earth combined.
A Bitcoin private key is simply a randomly selected 256-bit number between 0x1 and 0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4140 (the order of the secp256k1 curve). That range contains approximately possible keys.
