WebSep 7, 2024 · Like greedy(), the function returns the optimal seed set, the resulting spread and the time taken to compute each iteration. In addition, it also returns the list LOOKUPS , which keeps track of how many spread calculations were performed at each iteration.

In each iteration, item j= argmax i2ZnY g logdet(L Y[fig) logdet(L ) (1) is added to the already selected item set Y g. Since L is a PSD matrix, all of its principal minors are also PSD. Suppose det(L Y g
WebMay 22, 2016 · In policy iteration algorithms, you start with a random policy, then find the value function of that policy (policy evaluation step), then find a new (improved) policy based on the previous value function, and so on. In this process, each policy is guaranteed to be a strict improvement over the previous one (unless it is already optimal). Given a policy, its … WebJan 25, 2024 · The sequences are initialized to be the observed reads. Example 1. Consider the example genome AGATTATGGC and its associated reads AGAT, GATT, TTAT, TGGC.
