Record Class TimeWindow

java.lang.Object
java.lang.Record
org.ddolib.examples.tsptw.TimeWindow
Record Components:
start - The beginning of the time window (inclusive).
end - The end of the time window (inclusive).
public record TimeWindow(int start, int end) extends Record
Represents a time window with a start and end time.

A TimeWindow defines an interval [start, end] during which an event, task, or visit must occur. Both start and end are inclusive and usually represented as integer time units (e.g., minutes, hours).

Typical usage is in scheduling problems such as the Traveling Salesman Problem with Time Windows (TSPTW), where each location or task has a limited time window in which it can be visited or executed.
