comment Is the function $f( x)=1/|x|^{1/2}$ Lipschitz continuous?
The stated $x_i$ don't work; eg if C = 1+e for small positive e, $|f(x_1)-f(x_2)| < C|x_1-x_2|$. However, $x_1 = \frac{1}{C^2}$ and $x_2 = \frac{1}{2C^2}$ work.

comment Problem on Divide-and-Conquer Relation
Although you say "Each player who loses in the first round gets nothing", the problem says "a player who loses in the first round gets $100".

comment Counting walks on colored graphs
Can you explain your $3*2^{k−1}$ walks on k 3-colored vertices formula? At least at k=1 and k=2 the numbers appear to be twice as large; e.g {br, bg, gr, gb, rg, rb} at k=1, and {gbg, grg, gbr, grb, etc} at k=2.

comment Algorithms and Simulation
Were you given a definition of "optimal"? Or any limitations? (I.e. for (b) it looks like $\sigma^2=1$ should be optimal for the obvious def of optimal)

comment Find the minimum number of links to remove from digraph to make it acyclic
An acyclic graph contains no cycles at all, rather than merely a vertex that's not in a cycle.
