Dynamic programming (DP) is an optimizing strategy commonly used in various discipline in science. It is widely used in biology to calculate optimal alignment between pairs of protein or DNA sequences. DP is so important, that it is core of many software applications available today for sequence analysis. DP algorithm is essential topic in many undergraduate and graduate bioinformatics course. Although simple in formulation, DP is not that easy for students to learn.

I am going to discuss the failings of the PREDIMED study, real and imagined. I will do this in a Question & Answer style. Several questions are inspired by theheart.org and NEJM comments and even statements by the low fat "gurus", Essselstyn, Ornish, McDougall or Pritikin. It is no surprise they are up in arms after the study has been published. It threatens their livelihood.... Read more »

This is not a study that has a valid control group to determine if there is any benefit from ventilation. There is no group that does not receive ventilations, so it is like a study of one type of blood-letting vs. another type of blood-letting with the researchers taking for granted that blood-letting does improve outcomes. That is not a problem if blood-letting actually improves outcomes.
Should we take it for granted that blood-letting improves outcomes and that the only hypothesis worth s........ Read more »
