comment What is wrong with this code?
You could just specify a PlotRange: i.stack.imgur.com/VvfsJ.png

comment A counterintuitive RegionPlot behavior
Can you explain why you say they are consistent? I already said why they are not.

comment A counterintuitive RegionPlot behavior
I think you have some confusion. In the first plot you specify the range $\alpha\in[-1,0],\gamma\in[0,1]$ and then crop the result using PlotRange to $\alpha\in[0,1],\gamma\in[-1,0]$. These ranges are disjoint so it is not surprising that nothing is visible.

comment Obtain polygons describing all intersections of many polygons
Another problem with an image processing approach is that if two edges intersect at a small angle you will get a chain of disconnected pixels: i.stack.imgur.com/TmEtp.png

comment Obtain polygons describing all intersections of many polygons
You could use a binary encoding: assign each shape a colour that has exactly 1 nonzero bit, rasterize each on a black background, then use ImageAdd. But you can only distinguish up to 24 shapes.

comment How to detect outlier in data of an unknown function $f(x)$
I don't think I would call the errors in your data outliers as such (i.stack.imgur.com/h6MwF.png). There seems to be a small systematic offset that comes and goes.

comment Visually Separating Cliques in Graphs
Instead of separating the cliques physically, have you considered colouring them using HighlightGraph, like in the example for FindGraphPartition?

comment Visually Separating Cliques in Graphs
Are your cliques disjoint, that is, no vertex belongs in more than one clique? Also, it would be nice if you could provide some example data.

comment Is there any way to solve this convex-concave like optimization problem?
First of all the question is how to even represent an arbitrary probability distribution $g$ in a numerics-friendly way. You might divide $\mathbb R$ into a finite number of bins and represent $g$ as the vector of probability mass in each bin, then approximate the integrals by sums over the bins. At least that way, you'd end up with a finite-dimensional optimization problem.

comment Is it possible to have a function with non-global parameters?
Wait a second... I've never heard of function parameter names colliding, in any programming language. Is that something that actually happens in Mathematica packages??

comment How do I display the plane of best fit in 3D?
Define fit = Fit[t1, {1, x, y}, {x, y}], then use Plot3D.
