DNA computer (Adleman 1994)

Realizes: Hamiltonian path via strand hybridization

Leonard Adleman's 1994 demonstration solved the directed Hamiltonian path problem using DNA strand hybridization. Cities encoded as DNA sequences, flight connections as complementary strands. Massively parallel biochemical search. Speed: hours to days (biochemical reactions). Capacity: combinatorial search problems (limited by DNA synthesis/sequencing).
