  1. Formal Models of Computation Running Haskell Programs – power

  2. How functional programs work… We have seen simple programs such as Let’s now see how they are executed Given the program above, we get the following: But how? power x 0 = 1 power x (n+1) = x * (power x n) power 2 3 8 formal models of computation

  3. How functional programs work… Execution: power x 0 = 1 power x (n+1) = x * (power x n) power 2 3 formal models of computation

  4. How functional programs work… Execution: power x 0 = 1 power x (n+1) = x * (power x n) 3matches(n+1), assigning 2 to n power 23 formal models of computation

  5. How functional programs work… Execution: power x 0 = 1 power x (n+1) = x * (power x n) power 2 3  2 * (power 2 2) formal models of computation

  6. How functional programs work… Execution: power x 0 = 1 power x (n+1) = x * (power x n) power 2 3  2 * (power 2 2) formal models of computation

  7. How functional programs work… Execution: power x 0 = 1 power x (n+1) = x * (power x n) power 2 3  2 * (power 2 2) 2matches(n+1), assigning 1 to n formal models of computation

  8. How functional programs work… Execution: power x 0 = 1 power x (n+1) = x * (power x n) power 2 3  2 * (2 * (power 2 1)) formal models of computation

  9. How functional programs work… Execution: power x 0 = 1 power x (n+1) = x * (power x n) power 2 3  2 * (2 * (power 2 1)) formal models of computation

  10. How functional programs work… Execution: power x 0 = 1 power x (n+1) = x * (power x n) power 2 3  2 * (2 * (power 2 1)) 1matches(n+1), assigning 0 to n formal models of computation

  11. How functional programs work… Execution: power x 0 = 1 power x (n+1) = x * (power x n) power 2 3  2 * (2 * (2 * (power 2 0))) formal models of computation

  12. How functional programs work… Execution: power x 0 = 1 power x (n+1) = x * (power x n) power 2 3  2 * (2 * (2 * (power 2 0))) formal models of computation

  13. How functional programs work… Execution: power x 0 = 1 power x (n+1) = x * (power x n) power 2 3  2 * (2 * (2 * (power 2 0))) formal models of computation

  14. How functional programs work… Execution: power x 0 = 1 power x (n+1) = x * (power x n) power 2 3  2 * (2 * (2 * (1))) formal models of computation

  15. How functional programs work… Execution: power x 0 = 1 power x (n+1) = x * (power x n) power 2 3  8 formal models of computation
