How do you convert non convex to convex?
Takeaway: try adding a variable to transform the non-convex problem into a convex one. where f,hi are posynomials and lj are monomials.
We can transform this to a convex problem with yi = log xi.

How do you know if a shape is convex or non convex?
To determine if a shape is convex, we can draw two points somewhere within the shape and see whether or not the line connecting them goes outside the shape.
If we can draw two points where the line connecting them goes outside the shape, then the shape is not convex, but rather concave..
Is concave and non convex the same?
A function is concave if -f is convex -- i.e. if the chord from x to y lies on or below the graph of f.
It is easy to see that every linear function -- whose graph is a straight line -- is both convex and concave.
A non-convex function "curves up and down" -- it is neither convex nor concave..
Is non convex and concave the same?
A concave polygon is a polygon which is not convex.
This polygon is just the opposite of a convex polygon.
A simple polygon is considered as a concave polygon if and only if at least one of the interior angles is a reflex angle (between 180\xb0 and 360\xb0).
It is also called a non-convex polygon..
What distinguishes a convex set from a non convex set?
Another way to verify if the polygon is convex or concave (non-convex) is to analyse the amplitude of the internal angles of the polygon.
If all the angles are inferior to 180\xba, it is convex.
On the contrary, if at least one angle is superior to 180\xba, the polygon is concave..

Convex Functions
A function is concave if -f is convex -- i.e. if the chord from x to y lies on or below the graph of f.

- Another way to verify if the polygon is convex or concave (non-convex) is to analyse the amplitude of the internal angles of the polygon.
If all the angles are inferior to 180\xba, it is convex.
On the contrary, if at least one angle is superior to 180\xba, the polygon is concave. - Quadrilaterals.
A quadrilateral is a plane figure bounded by four straight sides.
This quadrilateral is called a convex quadrilateral because none of its four interior angles is a reflex angle.
This quadrilateral is called a non-convex quadrilateral because one of its interior angles is a reflex angle.
