👉 In mathematics and computer science, a semisegment is a piece of an interval that can be interpreted as either the end point of an open interval or the start point of an closed interval. This type of semisegment is used in various applications such as signal processing, circuit analysis, and machine learning. For example, if we have an interval [a, b] with endpoints a and b, then a semisegment can be defined as the set of all values between a and b that
