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. WebSep 20, 2024 · This course covers basic algorithm design techniques such as divide and conquer, dynamic programming, and greedy algorithms. It concludes with a brief introduction to intractability (NP-completeness) and using linear/integer programming solvers for solving optimization problems.
