Python Greedy -- Interval Scheduling - Non-overlapping Intervals

WebJun 21, 2024 · To solve this question, let us first write an equation to calculate the total time it takes for N tasks. This equation is: t = m 1 + a 1 + max ( (a 2 + m 2 - a 1 ), (a 3 + m 3 - a 2 ), ...). The first part of this equation (m 1 + m 2 + ...) is the time it takes for the first task. The second part of the equation is more complicated.

WebWhen the weights are all 1, this problem is identical to the interval scheduling problem we discussed in lecture 1, and for that, we know that a greedy algorithm that chooses jobs in order of earliest ﬁnish time ﬁrstgives an optimal schedule. A natural question is whether the greedy algorithm works in the weighted case too. Web(b) Using the approach that we used for the proof of correctness of the Interval Scheduling greedy algorithm prove that your algorithm indeed produces an optimal solution. Your proof needs to be clear and precise, in addition to being correct. 2. A variant of the Interval Scheduling problem is one in which each interval has an associated

The heuristic is: always pick the interval with the earliest end time. Then you can get the maximal number of non-overlapping intervals. (or minimal number to remove). This is because, the interval with the earliest end time produces the maximal capacity to hold rest intervals.
