You are a given a unimodal array of n distinct elements, meaning that its entries are in increasing order up until its maximum element, after which its elements are in decreasing order. Give an algorithm to compute the maximum element that runs in O(log n) time. 输入格式: An integer n ...
On the Signed (Total) k-Domination Number of a Graph We also present sharp lower bounds on the signed k k -domination number and signed total k k -domination number for general graphs in terms of their minimum and maximum degrees, generalizing several known results about signed domination......
Another often used estimate, particularly in emission image reconstruction, is the maximum a posteriori probability (MAP) estimate. This estimate is obtained by considering a uniform cost function given by (132)C(ŗ1,ŗ2)={0if|ŗ1−ŗ2|≤Δ1otherwise where Δ is small positive number....
In order to search the entire power-duty cycle curve (P-Dcurve), the initial pollens need to be distributed in the entire duty cycle range. The choice of pollen numbermis important for the global search. Larger numbermimproves the probability of finding the global optimal solution but leads ...
