0-1 backpack problem: A thief in the theft of a shop, found that there are n items, the value of the article I item VI, heavy WI-lb, where VI and WI are integers. He hopes to take away the goods the more valuable the better, but his backpack can only be loaded W-pounds of Things, W is an integer. What kind of things should I take? This problem is called the 0-

In fact, I saw this in LINUX as early as I saw it. Later I also saw something similar in the MFC memory pool. I also wrote a similar small memory pool according to MFC, (MFC uses return this + 1) later, I saw a similar definition in Li xianjing's System Programmer growth plan, So I thought about it as a summary, the results showed that some cool people on the Internet had already summarized it very well, so it turned around. Thank you for your sharing

Original Address:IOS lbs feature detailed [0] (get latitude and longitude) [1] (get current geo-location textKojiro SasakiBecause the function of lbs is to be used on the recent project. So I did a bit of pre-research. in general, the LBS function is generally divided into two pieces, one is geo-positioning, is to obtain the current accuracy, latitude and location of the function, this part of the function

advantage of IE may be that its compatibility is good, firefox's biggest advantage may be its adherence to standards. Which of the following is important to standards and compatibility? I think common users need compatibility most. Don't make it so complicated. Advanced users may be sharp, everything has to follow the rules and regulations. I think it's just like a joke on the internet, Microsoft Firefox or Firefox IE. It itself is a problem of 0 an

Given a group of items, each item has its own weight and value. within the defined total weight, how can we choose to make the total price of the item the highest. Solution: value density PI/wi (PI indicates the value of the item I, and WI indicates the weight of the item I) greedy algorithm. This selection criterion is: select the item with the highest PI/wi value from the remaining item. 0/1 the knapsac

maximum value that can be loaded, is still 0, because the item e,d is not the backpack can be installed.In the same vein, c2=0,b2=3,a2=6.For the 8 load-bearing backpack, a8=15, how to draw?According to the state transition equation of 01 knapsack, we need to examine two values,One is f[i-1,j], for this example is the value of B8 9, the other is f[i-
