Text evolution: Modeling DNA replication mechanisms with text

  1. 1. TextEvolution: Modeling DNA replication mechanisms with text Science Hack Day SF 2013 David Harris
  2. 2. Mutations and repairs • Point mutation -> letter substitution • Insertion mutation -> letter insertion • Deletion mutation -> letter deletion • Repair -> spellcheck and replace “broken” words with best guess at correct word (sometimes you get a favorable mutation)
  3. 3. Parameters • Do nothing rate • Point mutation rate • Insertion rate • Deletion rate • Number of generations
  4. 4. Examples • From so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved. • Fro simple beginning endlessness Dost beautiful and Yost Wonderful been and bing evolved • Simple beginning endlessness Dost Beautiful Wonderful beebread evolved • beginning godlessness Beebread Evolve
  5. 5. Examples • An American monkey, after getting drunk on brandy, would never touch it again, and thus is much wiser than most men. • Americana monkey after getting drunkenness ditch against embouchure ooze Chaw most men • Americana Asterisking drunkenness Chauvinist
  6. 6. Examples • I have tried lately to read Shakespeare, and found it so intolerably dull that it nauseated me. • Haversack laxity raped fun so intolerable deal Cronkite nauseated me
  7. 7. Examples • I love fools' experiments. I am always making them. • lovelinesses allay marring Oh • lonelinesses Earring
  8. 8. Lessons • Mutations often kill off species (words) • Having an insertion or deletion rate too high very rapidly kills off species (words) • There are some bizarre words in the English language
