CSC263 Assignment 3 Question 7

We consider undirected graphs (with no weights). 
Often there are multiple shortest paths between two nodes of a graph.

Describe a linear-time algorithm such that, given an undirected, unweighted graph 
and two vertices u and v, the algorithm counts the number of distinct shortest paths 
from u to v. Justify its correctness and the running time.

Describe an implementation of the BITREVERSEDINCREMENT procedure on A that allows 
the bit-reversal permutation on an n-element array to be performed in time O(n).

Note: compile needs -lm flag for <math.h>:
gcc -Wall -o kbit_rev_permute kbit_rev_permute.c -lm

CLRS 22-4

Let G = (V,E) be a directed graph in which each vertex u in V is labeled with
a unique integer L(u) from the set {1, 2, ...|V|}. For each vertex u in V , let
R(u) = {v in V: u has a path to v} be the set of vertices that are reachable from u. 

Define min(u) to be the vertex in R(u) whose label is minimum, i.e., min(u) is the vertex v such that L(v) = min{L(w): w in R(u)}. Give an O(V+E) algorithm that

Suppose that we wish to add the operation PRINT-SET(x), which is given a node x
and prints all the members of x’s set, in any order. Show how we can add just
a single attribute to each node in a disjoint-set forest so that PRINT-SET(x) takes
time linear in the number of members of x’s set and the asymptotic running times
of the other operations are unchanged. Assume that we can print each member of
the set in O(1) time.

I always forget how to do this on a new system:

export CUDA_PATH=/usr/local/cuda-9.2
export CUDA_HOME=/usr/local/cuda-9.2
export LD_LIBRARY_PATH=/usr/local/cuda-9.2/lib64

I always forget the basics of screen:

See what's currently running

screen -ls

Make a new named screen session, do stuff, detach

screen -S nameofsession

Note

This is a note to self of setup steps when purchasing a new domain on Namecheap, pointing its DNS to Route 53, requesting an SSL certificate, and setting up a CloudFront distribution for it to point to an S3 bucket.

1. Point NameCheap domain Custom DNS to Route 53

Create a new hosted zone for the new domain in Route 53. Will be given the correct nameservers to use under record type 'NS'. Add these values in NameCheap under 'Custom DNS'.

2. Request new SSL certificate for example.com and *.example.com
