QUASICONVEX Meaning and
Definition
-
Quasiconvex is an adjective used in mathematics and optimization theory to describe a specific property of a function. A function is said to be quasiconvex if, for any two points in its domain, the function value at any point on the line segment connecting these points lies above the lower of the two function values at the endpoints of the line segment. In simpler terms, a function is quasiconvex if its graph lies above any of its sub-level sets.
In other words, if we have a quasiconvex function, regardless of the two points we choose, the function value is always increasing or constant along the line segment connecting them. Unlike a strictly convex function, a quasiconvex function does not necessarily have a unique minimum value, as it may have multiple local minima. However, it is guaranteed to have a global minimum.
The term "quasiconvex" comes from the Latin word "quasi," meaning "almost" or "resembling." Quasiconvexity is a generalized concept that relaxes the strict requirements of convexity, allowing for more flexibility and wider applicability in various optimization problems. It finds applications in economics, engineering, operations research, and other fields where optimization plays a central role.
In summary, a quasiconvex function is one that maintains a certain order of values along line segments, providing a useful tool for analyzing and solving optimization problems.

Etymology of QUASICONVEX
The word "quasiconvex" is derived from the combination of two terms: "quasi" and "convex".
1. "Quasi": This prefix comes from the Latin word "quasi", meaning "as if" or "almost". It is commonly used to indicate a resemblance or similarity to something but without being exactly the same. In mathematics and other disciplines, "quasi" is used to convey the notion of approximate or near, without being fully identical.
2. "Convex": This term is derived from the Latin word "convexus", which means "bowed together" or "arched". It refers to a geometric concept where a set, function, or curve lies entirely or partially on one side of a supporting line or hyperplane. Essentially, it implies that any two points within the set can be connected by a straight line segment that is also within the set.
