Problem Detail: I have the following question, but don’t have answer for this. I would appreciate if my method is correct : Q. When searching for the key value 60 in a binary search tree, nodes containing the key values 10, Read More …

Problem Detail: Let $D=(V,E)$ be a finite directed graph with no isolated nodes(from every node there is at least one edge entering and one exiting). For $v in V$ define the following sets: $$v^+= left{w in V|(v,w)in E right}, v^-= left{w Read More …

Problem Detail: I am reading Michael Sipser’s book Introduction to the Theory of Computation, which mentions the set $$S = { n mid text{$n$ is an integer and $n = n + 1$}}.$$ This doesn’t make any sense to me. I Read More …

Problem Detail:  Context I’ve been programming in java for a few years now. And atm i’m learning something totally different: Clojure. There the expression problem can be solved by using multimethods whereas in java you will need something like the Read More …

Problem Detail: A typical generational garbage collector keeps recently allocated data in a separate memory region. In typical programs, a lot of data is short-lived, so collecting young garbage (a minor GC cycle) frequently and collecting old garbage infrequently is a Read More …

Problem Detail: How is a hypergraph different from the bipartite graph generated from the hypergraph by introducing new vertices for each hyperedge, and connecting these vertices with the vertices connected by the original hyperedge. Alternatively, I could also start with a Read More …

Problem Detail: Could someone, in plain english, explain the distinction between the fundamental matrix and the essential matrix in multi-view computer vision? How are they different, and how can each be used in computing the 3D position of a point imaged Read More …

Problem Detail: For a certain problem I am trying to solve given a list of integers, it is advantageous to me to first identify as many of the integers that are mutually coprime as possible. I’m having trouble thinking of a Read More …

Problem Detail: From Van Emde Boas trees lecture: We will use the idea of superimposing a tree of degree ${u^{1/2}}$ on top of a bit vector, but shrink the universe size recursively by a square root at each tree level. The Read More …
