My younger son and I have been studying angles for the last week. I decided to run through a few clock problems for a review. The secret about this exercise is that all three problems are pretty much the same problem in a slightly different form. Question 1: How many degrees does the hour hand…

Items I_i s (+ve integers, I_i \in [1,U]) arrive one after another, and for any n, after having seen n items, you have to return an approximation to H_n which is the H-index of the first n items. I_1,...,I_n (The H-index of a set of number is largest k such that there are at least k items each >= k). A student in Rutgers posed this problem.This problem has a simple worstcase solution: sing log_{1+\eps} U space, get (1+\eps) one-sided error approximation by maintaining

Dyadic relations enjoy yet another form of graph-theoretic representation as labeled bipartite graphs or labeled bigraphs. I’ll just call them bigraphs here, letting the labels be understood in this logical context. The figure below shows the bigraphs of the 16 … Continue reading →
