If one of the endpoints is included in the interval, it is considered a half-open interval or a half-closed interval. These terms are both used. If the previous example included the number 2 but not the number 3, it can be expressed using the inequality 2 ≤ x < 3. This interval wo...
Closed and open intervals complement each other in the sense that any real number can be in a closed interval, an open interval, or both. For example, the real number 3 is in the closed interval [1, 4] and the open interval (1, 4). The empty interval 0 and the interval of all ...
The open interval is represented using parenthesis - ( ), and the closed interval is represented using box brackets - [ ]. The open interval and closed interval are represented in the form of an expression. The open interval is represented as x ∈ (a, b) or a < x < b, and the ...
A poset P = (X, a parts per thousand(0)) is a unit OC interval order if there exists a representation that assigns an open or closed real interval I(x) of unit length to each x a P so that x a parts per thousand(0) y in P precisely when each point of I (x) is less ...
