comment How to plot feasible objective space of a Generic Multiobjective Optimization problem?
Can you give the definition of "feasible design space of objective functions" for those of us not intimately familiar with multiobjective optimization terminology?

comment How to make a cylinder with bottom that shows hidden part of edge as dashed curve
Oh man, that ViewPoint -> Dynamic[vp] trick is neat. I know I'm going to be using that in the future.

@belisarius: I don't think "be ignorant of" is one of the meanings of the verb "ignore"...

comment Efficient Lloyd Sampling of Images
Apparently the weighted CVT works pretty well nevertheless. See the paper "Weighted Voronoi stippling" by Adrian Secord, which I think you will find quite interesting and relevant.

comment Efficient Lloyd Sampling of Images
Your algorithm converges to a Voronoi diagram in which every site is the intensity centroid of its cell, which is not the same as a Voronoi diagram in which every cell contains approximately the same total intensity. Observe that even for a constant intensity, the result is a centroidal Voronoi tessellation whose cells can have different areas.

comment How I calculate the volume of multiple intersecting spheres?
Do you want the volume of the intersection of the spheres, or the volume of the union of the spheres (which happen to be intersecting)?

Use the options "MeshElementType" and "MeshRefinementFunction".

comment A better “VisibleSpectrum” function?
It seems the internal functions are only available after you call ChromaticityPlot once. Is that normal?

The question is a bit unclear (squiggly marks on a graph is not a substitute for a precise specification) but this previous question seems related: mathematica.stackexchange.com/q/22528/484

comment Mollweide maps in Mathematica
Is there an inverse of GeoGridPosition? ImageTransformation is much faster than ImageForwardTransformation, I think.

Also, less chance of writing the equations wrong.

comment Probability of multivariate normal being positive on each coordinate
I eagerly looked up your book because I wanted to see "more detail"... but there isn't any more detail, just a restatement of the same formula and a reference to Stuart and Ord's book.
