I use DP for multiple methods.
As the longest descent subsequence. I asked other people, who have a tree-like DP and use the shortest path for differential constraints.
There is also a two-dimensional backpack problem.
The longest monotonic subsequence, long, wide, and high x, y, and z are enumerated into six. Then sort and find the longest monotonic subsequence.

According to Genesis, the Tower of Babylon is the second engineering feat of mankind following Noah's Ark, but the tower of Babylon is also the first project to be completely failed. Why are projects with clear goals and adequate human and material resources still failing at the end? The management lesson presented to us by the tower of Babylon is the lack of com
The four ancient civilizations have been very revered by me, and they have created countless magnificent images on this beautiful planet.

Mathematical principle derivation: f (x) = x2-n---formula (1) n is a value that requires a square root, such as the square root n = 100, which requires 100, so the problem is converted to the 0 point of F (x), the derivative of f (Xn) is the slope of xn+1 so there is a formula so xn+1 = X N-f (Xn)/F ' (Xn) substituting Formula 1 F (Xn) =x2-nf ' (Xn) =2xxn+1 = Xn-(xn2-n)/(2Xn) = XN-1/2 (Xn-n/Xn) = (Xn + n/xn) Xn is a guessed number n is a value that requires a square root after several iterations
Question: uva437-The Tower of Babylon (DP on DAG)
Here are some cubes for you and XYZ for length, width, and height. Now, I hope you can fold these cubes to maximize the final height, and these cubes can be used infinitely, but if a cube needs to be on the top of another cube, the bottom of the cube must be completely contained in the bottom of the cube.
Solution: in fact, unlimited use is useless here, because a cube can be used up to three times a

That's not very surprising, since snowboarding is really great. The bad thing is, and the gain, the area must slide downwards. Another disadvantage is if you've reached the bottom of the hill you had to walk up again or wait for the Ski-lift .Michael would like-to-know how long the longest run was in.

A variety of methods, I do with DP.I do it as the longest descending subsequence. Asked the other person, there is a tree DP, there are differential constraints with the shortest.There are two-dimensional knapsack problems.The longest monotone subsequence, with a length-width high of x, Y, and Z, is enumerated as six. Then sort, and find the longest monotone subsequence.#include POJ 2241 The Tower of Babylon (UVA 437)
Test Instructions:Given some cubes, for two cubes, only one of the two sides of the bottom is strictly less than the other one can be placed above it. The maximum height that can be obtained.Ideas:A cube can be turned into 6 different rectangles with different weights (heights) on the bottom, and then the nesting of these rectangles. It used to turn the problem into the longest way on a DAG map, and this time the rectangles are sorted by the bottom area from small to large, and then the problem
The algorithm is as follows:1. Guess the square root of a required number2. Using the original number/guessing number3. Use the value of the calculated step 2 and the average of the guessed number4. Step 3 Gets the value for the new Guess value5. Determine if the new guess value is the same as the original guess value, the same jump to step 2, the difference is that the guess value is the square root of the original number# same as different in computer, reference floating point number same meth
