Berlekamp invented an algorithm to factor polynomials and the Berlekamp switching game, and was one of the inventors of the Berlekamp–Welch algorithm and the Berlekamp–Massey algorithms, which are used to implement Reed–Solomon error correction. He also co-invented the Berlekamp–Rabin algorithm, Berlekamp–Zassenhaus algorithm, and the Berlekamp–Van Lint–Seidel graph.
Berlekamp had also been active in investing, and ran Axcom, which became the Renaissance Technologies' Medallion Fund.
