設(shè)T 是一棵帶權(quán)樹,樹的每一條邊帶一個(gè)正權(quán)。又設(shè)S 是T 的頂點(diǎn)集,T/S 是從樹T 中 將S中頂點(diǎn)刪去后得到的森林。如果T/S中所有樹的從根到葉的路長都不超過d ,則稱T/S 是一個(gè)d 森林。 (1)設(shè)計(jì)一個(gè)算法求T的最小頂點(diǎn)集S,使T/S是d 森林。(提示:從葉向根移動(dòng)) (2)分析算法的正確性和計(jì)算復(fù)雜性。 (3)設(shè)T中有n 個(gè)頂點(diǎn),則算法的計(jì)算時(shí)間復(fù)雜性應(yīng)為O(n)。

最佳高度問題。 問題描述: 假設(shè)有n個(gè)任務(wù)由K個(gè)可并行工作的機(jī)器完成。完成任務(wù)i需要的時(shí)間為t(i)。試設(shè)計(jì)一個(gè)算法找出完成這n個(gè)任務(wù)的最佳調(diào)度,使得完成全部任務(wù)的時(shí)間最早。

Expert Choice represents a significant contribution to the decision making process 工t assists a decision maker in solving complex problems involving many criteria and several courses of action . An Expert Choice solution to a problem reflects the expertise of the decision maker , not the computer . Behavioral scientists have spent many years studying the human mind and how it makes decisions . They have found that humans are influenced by their previous experiences and this causes them to have biases . Basic instincts , preferences and environmental factors also play key roles in how we analyze data and make decisions . There 15 way to remove these factors from human decision making , nor would we necessarily want to , but as the problems of our world become more and more complex , it 15 necessary for us to employ a framework to help make more logical and less biased decisions while still taking our feelings and intuition into consideration .
