Assignment 4. (Due on Friday of Week 14. Drop it in Mail Box 63 )

Assignment 4. This one is cancelled since there is a solution on website. I new assignment will be given on Nov. 28. (Due on Friday of Week 14. Drop it in Mail Box 63 ) This time, Professor Yao and I can explain the questions, but we will NOT tell you how to solve the problems.

Euler and Hamilton's

Euler and Hamilton's. Paths and circuits. Euler Paths. An Euler path is when a trail on a graph visits each edge exactly once. An Euler path must have an odd amount of degrees, and if the Euler is connected and has an even amount then it has at least one Euler circuit.
