Problem:There are n items and a backpack with a capacity of V. The value of article I is c[i] and the weight is w[i]. The solution of which items are loaded into the backpack makes these items less than the total weight of the backpack and the maximum value.The problem is characterized by the following: Each item has only one piece, can choose to put or not to put. Use f[i][j] to indicate that the backpack current capacity is J, choose the maximum value when loading

The two days to learn the timer of the lpc2103. I started to look at the previous register introduction. I felt dizzy and I was confused later. However, when I see the following operations using the image to describe the timer-related registers, it will be clear. After you know the application, you can see the principle again. Why are these two timers put together, because they are both 32-bit timers, which are the same except for the peripheral base address. Let's talk about the features of th

DescriptionTry to design a function of searching a subset space tree by backtracking method. The parameters of the function include the necessary functions such as the node feasibility determination function and the upper bound function, and use this function to solve the 0-1 knapsack problem. 0-1 backpack The problem

Read the source code of monitorserver and record some experiences. Start with the main function and start with the following code lines: 1 struct sigaction sa;2 sa.sa_handler = SIG_IGN;3 sigaction( SIGPIPE, sa, 0); I have never used it before. I don't know why I ignored the sigpipe signal, so I searched for it and explained it as follows: When writing a socket program in Linux, if you try to send it to a

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-

Consult W3school, and the answer is: Math.random () returns a random number from 0 to 1, which is (0,1).Review the MDN (Mozilla Developer Network), and the explanation is: Math.random () returns a random number greater than or equal to 0, less than 1, or [0,1].And in fact? Let's do an experiment: Cycle through Math.ran

First of all, I would like to thank my brother Xiaoxiao for helping you. Directly give the state transition equation: DP [I] [v] = max (DP [I-1] [v], DP [I-1] [V-Vol [I] + val [I]); Vol [I] is the volume of the I-th item, and Val is the value of the I-th item The equation means that when we consider the I items, there are only two options for I items: Put or not put, if not put the weight is the weight of
