@chubakueno edited the problem above, if you're still interested. I'm particularly interested in the pattern for $n=4, 5, 6, 7, 8$; I'm confident that my best value is the actual value for those (unless I've written my exhaustive search wrongly). Tell me if you have any ideas!

@GerryMyerson is it true that only linear functions can satisfy the third condition?

comment Is having the sum of each column zero a sufficient condition for a matrix to be singular?
My inspiration for this question was my observation that the transition matrices for Markov processes that I was working with always had an eigenvalue 1. I'd be happy to see counter-examples, though - I'm not 100% sure that my conjecture is correct.

comment Number of paths in a grid
@WouterM. I'm now not sure that the number I generated was correct, it may have been an error in my code that i used to count the number of paths. Gerry - I think the oeis link you posted is exactly what I was looking for. Let me get back to my code and check it again.

comment Economics - Function satisfying two conditions
I've been trying to construct a function where $x_{1, opt}$ and $x_{2, opt}$ do not scale in the same way. I haven't been successful in finding one when trying separable functions $f(x_1, x_2) = g(x_1) + h(x_2)$.
