comment Can mathematica simplify an expression setting simplified answer equal to zero?
Perhaps this is what you are looking for? Is is possible to have mathematica move all terms to one side of an equation?

This reminds me of Richard Schwartz's book You Can Count on Monsters.

comment Determining all possible traversals of a tree
@Andrew We can also replace the first definition of f by f[tree_List] := List@@@Flatten@Apply[lst, f[{}, tree], {-2}];. Now f will work for {423,{53,66,424}} as well as {423, {{53, {39, {66, {67, 81, 423}}, 423}}, {66, {67, 81, 423}}, {424, {25, 40, 423}}}}.

comment Convert head Times to List
I am just wondering if you have a rule of thumb to recognize when to use Hold as opposed to Unevaluated.

comment Convert head Times to List
Generally. I know that Unevaluated dissolves after we pass it through a function, but are there other considerations to keep in mind?

comment Mathematica for Computer Scientists
Gray's "Mastering Mathematica" has a nice chapter on rule-based programming followed by a discussion of substitution and Lambda calculus, so you may want to check that out.

comment Implementing a function which generalizes the merging step in merge sort
I am still developing my feel for efficient programs, so it helps to look at other implementations even if they are not the fastest possible. Leonid's commentary also adds value to your answer. +1
