I would apply if I were you - you never know what will happen. You also should read the gradschooltalk paper by a professor at CMU (who also was in the admission committee of schools like Berkeley, MIT). Overall she emphasizes in researching which you have plenty. In fact, I know several students at CMU and they also concur that they really look for research potential for Ph.D admissions. BTW, I am also applying to CMU - we'll see how it goes within a few months.

Having double majors is generally good. In the U.S., one major generally takes 4 years and double majors take about 5 years. You still have sometimes before graduation - probably want to improve your GPA. A 'C' in average doesn't look good. Also the reputation of your current school also takes in account.

It's hard to say :] every thing counts and varies among universities. The results can be quite surprising ! Based on what posted, you have pretty good research experience and good academic status so don't worry too much. From quick glance, you seem to miss the deadlines of many schools in that list.

I would think that USC is among the Top C.S. schools (at least comparable to those listed in your Top list).

I think they look at the most recent (one of the schools I applied to say they look at the best).

66% quant is slow for science/engineering studies in general. However even if you have 100%, that doesn't mean much (well actually it means you are able to do 20+ 8th grade math problems within 45 minutes). Although I do suspect many schools use GRE scores as threshold for cut-offs, also for TA-ship and such. In addition, it seems 'public' schools worry more about GRE scores than 'private' , since they have to answer to the government which provides them fundings and the government wants good admission statistic. The GRE scores are pretty standard.

It's really hard to evaluate anyone's profile since no one actually knows exactly how the admission works. In short, it depends (on you, the mood of the adcom, the quality of applicants of that year, etc). All I can say is your academic status is good (4.0 GPA during your M.S.). Probably apply to several more schools just in case. Do you have any research experience, any project (e.g., M.S. thesis) ? Talk about those. And since Your GRE isn't competitive to most others so perhaps you should add schools like MIT, UIUC, Purdue to your list ?

Just found out Purdue also does not require GRE general scores (Ph.D.)

Ph.D. program

Hey fellow applicants - which universities in the U.S. don't require GRE (general) scores ? So far I've found that MIT and UIUC don't require these. Any other ? Thanks,

use both

as long as that conf doesn't accept randomly-generated paper it should look good and bolster your research potential/experiences.

1) do you know anything about x? I had some mistype in this question, can you please take a look again ? 2) The answer depends on the parity of n Oh, I see ... I read it as n is a positive EVEN integer. These mistakes costs me many easy questions. In addition I often make mistakes such as 45/80 = .55 something like that. Do you know how to deal with these mental problems ? 3) You have an extra 0 in the first product first term, that I suppose shouldn't be there. Yes - that 0 shouldn't be there. In general, the product a*b with a+b constant gets bigger as the two numbers get closer to each other. (has to do with the square having the biggest area for that perimeter). The numbers in the second pair are closer to each other 4) Taking at least one class = 24 + 40 - 20 = 44 Taking no class = 80 - 44 = 36 Probability of getting one of these = 36/80=0.45 I hope this helps.

That's an assumption - hence I was asking about the size of the set S. I interpret it as any fraction that is n/(n+1) with n less than 20 can be in set S. And as thus all fractions that fits the rule described in set S are 1/2 2/3 ...19/20

1) what's the cardinality (size) of set S ? Assuming it's from n =1 to n =20 , 20 members (e.g., 1/2 , 2/3 3/4 ... 19/20) then prod of all of them == 1/20 as 1/2 * 2/3 * 3/4 ... 19/20 is easily reduced to 1/20 (2 cancel out 2 3 cancel out 3...)

1) f(x) is the greatest integer less than or equal to x. c(x) is the least integer greater than or equation to x. 1/2(f(1.4)+c(1.4)) > 1.4 ; how? 2) a_k = 1 - (-1)^k . k is positive integer n is positive integer a_n ? a_(n+1) ; ans: cannot be determine . Why ? 3) 100,210 x 90,021 is less than 100,021 x 90,210 . How to determine this quckly ? 4) In a group of 80 student, 24 takes class A, 40 takes class B and 20 takes both. If select a student randomly from this group, what's the prob that person is NOT enrolled in EITHER classes ? Ans (.45)

they would meet 5 hr later which is 1 am; which is not among the answers ? 50x+70x=600 x=5

This is interesting ... so from this I can say the # of 8 occurs in 'x' consecutive numbers is 1/8 * x ? One more question left => 2) a city has population 7365000 in 1980, if it is increased by the same amount from 1980 to 1988, then its population in 1988 = ? The ans is 776000

Sorry once again I wrote the question incorrectly, please recheck below 2) a city has population 7365000 in 1980, if it is increased by the same amount from 1980 to 1988, then its population in 1988 = ? The ans is 776000 I believe it's the 1st 1000 positive integers. How do you solve it ? Thanks

how did u presume the values of N &M? Actually that's how I usually approach a problem, before get down to set up equations and do the hard works, I usually scanned through the answers and see if something stand out. In this case , 2/3 for N , which means 4/3 for M . From there everything matches since (4+2)/3 = 2 and 4^2 is 4x 2^2. N^2 = 4/6 ; shdnt it be 4/9? M^2 = 16/6 ;shdnt it be 16/9? yep, N^2 = 4/9 and M^2 = 16/9, I was doing it quickly and miscalc :) But M^2 is still 4x N^2 .

2 and 3 ... anyone ? I think I wrote 6) incorrectly. It should be n=28^3 , the answer is the unit dits of n is LESS than 4. I still don't get this , 28^3 = 21952 . I totally misunderstood 5, I keep thinking the boundary refers to the 'side' of the square or the diameter of the circle.

N = 2/3 M = 4/3 N^2 = 4/6 M^2 = 16/6 which is 4/6 * 4 (which fits the description M^2 is 4 times larger than N^2) In addition, N+M = 2 as 2/3+4/3 = 6/3 = 2

1) 72.42 = k(24 + n/100) , n 2) a city has population 7365000 in 1980, if it is increased by the same amount from 1980 to 1988, then its population in 1980 = ? The ans is 776000 3) if a number is chosen randomly from 1000 positive integers, what's the probability that it is a multiple of 2 and 8 ? Other than do the hard way of calculating everything out , e.g., 16 24 32 .... . Is there a quicker way ? 4) Given the letters A B C D E F, there are 20 diff 3-letter subset (20 choose 3). What is the # of 3 letter subset includes the letter F ? Answer = 10 5) Boundary of a level garden is designed to be 100 feet long. Circular area vs Square area of this garden. Ans Circular area is larger 6) n = 28^2 , unit dits of n is LESS than 4 Thanks in advance

I am more optimistic than nomad about your case since most undegraduates wouldn't have the opportunity to accomplish a research with high quality results to be presented in a prestigious journal (not to mention the time it takes to get into a journal). As long as your research experience is solid, and very good recommendations about your research potential. In addition, you might look at presenting your research at several good conferences (as full or late breaking papers). Have you considered the ACO group at CMU ? It seems to be among the top (if not the best) in combinatorial and theoretical related programs. Take a look at their faculties (the Blum's, M. Tricks, and so on). Similar to top notch schools, CMU takes GRE very lightly. Take a look at Mor Harchol-Balter's CS Ph.D guide, I think it is the best guide for aiming at 'good' schools since the author herself has been in the adcom of several top schools (including MIT). Good luck,

care to share what your potential schools are ? best of luck ...
