说明：  各位大虾，最近要做一个小组研究，可是网上搜了很久都找不到可行的答案。本人是初学matlab，能力实在有限，恳请各位大虾门帮帮忙帮我写一段代码吧…… 问题：这是一个组合拍卖最优化问题，对m个物品的任意组合有n个报价，要求拍卖者利益最大具体数学式子可简化为： max xi*pi(求和)i=1,2,..n s.t. (求和)xi(i|k属于Si)<=1 k=1,2,....m xi属于{0,1} m为物品数，n为竞标个数，xi代表竞标i是否入选竞胜标，pi是竞标i的价格，Si是i所提出的竞标组合。 其实这类似于一个背包问题，但头疼这个约束如何处理？ :'(求帮助求指导 之前发过一个帖子没有得到解决，在此再发一次
(Prawns, you have to do a group study recently, but you haven't found a workable answer online for a long time. I am a beginner MATLAB, the ability is really limited, I urge you to help me write a code. Problem: This is a combinatorial auction optimization problem, and there are n quotations for any combination of M items. The specific mathematical formula for the maximum interest of the auctioneer can be simplified as: Max xi*pi (summing) i=1,2,..n S.T. (summing) Xi (i|k belongs to Si) <=1 k=1,2,....m Xi belongs to {0,1} M is the number of items, n is the number of bidders, Xi represents whether I is selected for bidding, PI is the price of bidding I, and Si is the bidding combination proposed by I. In fact, this is similar to a knapsack problem, but how does it deal with headaches? : '(ask for guidance) A post has not been solved before, and I will send it here again.)
