comment Unbounded “polygon”
Thanks. Is there a way to specify that the polygonal domain is unbounded only in two sides, similar to a quarter-plane?

Added the "optimization" tag because the question is also about maximization/minimization

comment What is the smallest possible angle of this polygon?
The contained square and the containing square are parallel; I added a clarification.

comment The square cover number and the number of horizontal sides
Thanks. Your condition seems sufficient, but not necessary (i.e. it is too strong) For example, consider this polygon: i.stack.imgur.com/05mqv.png It has 10 horizontal sides but its cover number is only 6, so the cover number is indeed bounded by the number of horizontal sides, although equality does not hold in the upper teeth.

comment The square cover number and the number of horizontal sides
@EricTowers: the general concept of covering a polygon with primitive units is explained in detail here: en.wikipedia.org/wiki/Polygon_covering I also added a definition to the question. What I added here, which is not in the general definition, is the covering of a "polygon" which is unbounded in one or more directions. For example, when a polygon is unbounded to the north and east, the covering squares may flow over to these directions (but not to the south and west). I also added illustrations which I hope are clearer than before.

comment Size of minimal covering, overlapping and disjoint
This makes sense, thanks. It seems the example must involve rotated rectangles (in contrast to the square case), since if the rectangle are parallel to each other, their intersection is also rectangular.

I think it comes from here: sciencedirect.com/science/article/pii/S0097316596901041
