In the specification for pset1 greedy, there was a link explaining how the round() function worked, but that appears to be dead now. However, you can still watch the walkthrough which contains many tips, including how and why to use round() (and how it relates to math.h). It is by the way translated into many languages if you find it difficult to follow.

Lectures are remade each year, but the psets remain mostly the same. The deadline for all psets (including pset1) is January 1. 2017, you probably won't finish the course by then, but you also won't have to redo the psets you have done, since only pset6-pset8 will change as far as I know.

Hopefully this answers your question, if there's anything you would like me to clarify though, just leave a comment :)

  • Good day everybody ! Does "you also won't have to redo the psets you have done" mean that even if we don't finish all course by Janyary 1st, 2017, we can then wait for next year's courses and not start from scratch ? (that would indeed be great :) ) – Julien Attard Oct 24 '16 at 3:01
  • Yes. The grades from all psets you have completed will carry over to next year's course, assuming the pset itself remains unchanged. – kluvin Oct 24 '16 at 5:41
