comment sudoku algorithm explanation formula
Hi zae and welcome to scicomp! I really don't think this is the best site for your question, since it deals with the algorithm to solve a game. It might do well in the game developers SE or the math SE site.

How do you define "interesting"?

That's so simple and it works! Thanks!

comment Is computer science a branch of mathematics?
@ApprenticeQueue: Isn't all mathematics essentially a collection of reductionist arguments?

comment Weird Al Yankovic's Partial Differential Equation
Interesting. Does the expression $4\pi\epsilon_0=1$ mean anything, physically?

comment Weird Al Yankovic's Partial Differential Equation
Is this formulated as an eigenvalue problem?

comment Is computer science a branch of mathematics?
@sashang: It is difficult to say one way or another if this is an oversimplification or not without establishing a rigorous and unambiguous definition of the word "branch" as it is applied by the OP's question. If you can provide such a definition, I can respond to your "oversimplification" claim more adequately, one way or another.

@SpYk3HH: The point is that the lines are blurred nonetheless, in spite of what most people believe of both subjects.

Do you seek a philosophical answer?

An elegantly succinct and informative answer using analogies from computer science! Kudos to you!

comment Incremental averageing
Can you elaborate on why precision errors are smaller in the second expression? Does the first expression contain a subtraction of nearly equal values?

comment Obtaining a bound on the differential operator
This almost makes sense. But the left hand side of the inequality uses $\frac{du}{dy}$, not $\left| \frac{du}{dy}\right|$. Unless it is somehow implicitly assumed that $\frac{du}{dy}>0$, I just can't see how we can conclude this.

comment Explaining the physical meaning of an eigenvalue in a real world problem
The question is about understanding and interpreting the eigenvalues/eigenvectors, not finding a method to solve the equation.

@AsalBeagDubh: I edited the question for consistency, replacing all instances of 'rum' with 'beer'.

comment Factorizing a saddle point operator
@ShuhaoCao: It is the divergence operator, but my current formulation is continuous, not discrete. For simplicity, I'm currently considering a 1D case where the divergence and gradient operators are equivalent. In the future, I'd like to consider higher dimensional cases where $u_1$ is, in fact, vector valued.

comment Factorizing a saddle point operator
@RobertLewis: LU is not favorable because the resulting discrete linear operator is large. I'm trying to avoid a large solve by splitting the continuous operator before discretizing the system.

comment Laplace equation with periodic boundary conditions
@Landscape: Indeed, this is what I suspected. But what of the form of the solutions? Are all solutions scalar shifts of each other if the periodic neumann condition is not imposed?
