I worry, somewhat, that male designers design more for men, and that perhaps female designers do so by osmosis. ,

This answer helps divide the long-term arcs into two categories: plot arcs that posit enigmas and mysteries, and relationship or character arcs that are more clearly delimited in the moment. ,

The guy apologized profusely. ,

It would be useful if you could put up our marks till date on MyEEE. We could get an estimate of where we stand

Awaiting solutions to the last HW :)

If we want to submit HW4 electronically, should we use the "Hwk2" AssignmentSubmission dropbox on EEE or will a new one be created? Or should HW4 only be turned in during class? Thank you.
Sorry; I've created a HW4 drop box if you need it. However, if you could also turn in a hard-copy in class (of anything except code) I'd appreciate it.

Hi Ben, You can refer to last quarter's slides while waiting for slides for this class. I mean CS271 in fall 2008 offered by prof. Dechter. Actually, the contents are almost identical.
Yes, my slides are based on slides from previous versions of 271, and those slides can be used if you don't want to wait for mine.

Wonder how long it'll take to get lecture slides posted. Bad bad bad
I don't see that waiting one day to get slides is such a big deal. How many people have started the homework?

I am sorry; my previous post mean: the textbook defines Quiescence as what the slides define (as the Horizon effect)*!

It seems like the textbook defines Quiescence as what the slides have defined (Pg 202 in the Second edition of the textbook). And I don't quite get what the textbook defines as the horizon effect if it is any different at all. Is my understanding correct?
Good question. Quiescence is a measure of how strong the horizon effect will be -- quiescent nodes will not suffer from a strong (short term) horizon effect. So the horizon effect is the notion that there is a distance beyond which the algorithm cannot "see", and quiescence is a property of a node that if we look only a little further our evaluation function will not change dramatically.

Does the min-conflicts algorithm always terminate? I remember how hill-climbing greedily picked a next solution and could get stuck in a local maximum. It seems that min-conflicts could infinitely loop, trying and moving variables without reaching a solution. Or are there bounds to the number of attempts?
Not always -- it can become stuck, and terminate at a non-solution, or can move randomly around a plateau. But it is effective with surprising frequency.

I think we all need the solution to homework 2 before the midterm. Could you upload the solution?
Done.

For Problem 2 on Homework 2, what did you mean by "for compactness, write each node as (abc;def;ghi)"? Did you mean draw a search tree and nodes in the tree should appear as letters rather than explicit 3x3 states of the 8-puzzle?
I simply meant that, rather than drawing an entire 8-puzzle square, you can just write each configuration "in order", say left-to-right and top-to-bottom. If you want to draw the entire square that's OK too.

It would be helpful if you can put up the midterm course online Thanks
I'm not quite sure what this means.

At least, could you upload lecture slides within the day we have a class? I would like to go over the materials while I can still remember them clearly.

probably you can release a version before class much before and if there are major changes then a second revised version.

yeah yeah yeah~ I agree.. eh.. I mean, I have the same Q as Kim( 13 Jan.) Thanks^^

Can we have powerpoints available before class so we can print them out from home?
Hmm. Fair question. I can try, but I'm not always done editing them. I'll see if I can get into the habit.

Will class powerpoint be available for download?
Yes; they're now posted on the syllabus.
