midsemester grades

We made a mistake when computing midsemester grades. Specifically, we used the wrong values for the programming portion of snakes. If you did substantially better (resp. worse) on the programming portion of snakes than on expression trees, then your midsemester grade will be higher (resp. lower) than the one on the HUB. If you did about the same on both assignments, your grade probably won't change. Sorry for the mistake. You can come to my office hours on Thurs if you want to see if your grade changed.

Office Hours Shortened

I have to give a presentation tomorrow at 7:00 pm. Due to this, my office hours will be shortened to ending slightly before 7, rather than 8.

Due to the fire alarm...

The second half of today's lecture will be covered next week. Please bring the printed slides from today's lecture to class next tuesday, so that I don't have to print them twice. Thanks! -c

Missed office hours

I apologize for missing office hours today, I will be holding additional office hours tomorrow (Tuesday) from 2pm to 3pm . Sorry for the inconvenience caused.

Compression Theory Assignment Correction

A mistake that made the LZW problem on HW3 (Compression) theory impossible to solve has been fixed (the first two given values in the compressed array should be 9 and 10, instead of 8 and 9). Please reload the TEX file if you have already downloaded it. Sorry for any inconvenience.

Midterm grades released

The min,max,mean, and median scores (out of 70 possible points) were 22, 65, 46, and 47 points respectively.
