Please refrain from using the bricklayer image here. It is demeaning, silly and wrong. In order to implement a mathematical model, a programmer has to:

  a) Understand the model.

  b) Come up with a fast algorithm for the specification.

  c) Prove the algorithm correct.

  d) Make no mistakes implementing the algorithm.

All of this has nothing to do with bricklaying. Moreover, it's quite ironic that the geniuses who come up with the models often "forget" point c) for their own work.
