Recent exposure to genetic algorithms and the use of genetic algorithms to find the optimal solution, so the relevant contents of the collation of records.Introduction to Genetic algorithms (excerpt from Wikipedia)Genetic Algorithm (English: Genetic Algorithm (GA)) is a search algorithm used in computational mathematics to solve the optimization, which is a kind of evolutionary algorithm. Evolutionary algorithms were originally developed from some phe

Dynamic Programming | Set (Optimal Binary Search tree) Given a sorted array keys[0. n-1] The search keys and an array freq[0. n-1] of frequency counts, where Freq[i] is the number of searches to keys[i]. Construct a binary search tree of the "All keys such" The Total cost of "all" searches is as small as possible. Let us-define the cost of a BST. The cost of a BST node are level of which node multiplied by its frequency. Level of root is 1. Example

A randomly generated 100BCell population, how many of them are Pareto optimal solutions. My answer is few, almost 0, and occasionally one or two, and I obviously feel like I'm mistaken somewhere. We say that Bcell A is better than Bcell B when and only if a is not inferior to B on each target and at least one target is better than B, which is the definition of Pareto optimal solution. Therefore, the non-inf

This article describes how to calculate the gray histogram of an image and perform binarization on the image, the binarization threshold values described in this article are all set by yourself. The threshold values set by yourself are often inaccurate, and the optimal threshold values for different images are different. So can the computer calculate the optimal threshold of the image? The answer is yes. Ne

To protect the natural environment on which humans depend, development of renewable resources (such as fishery and forestry resources) must be moderate. A reasonable and simplified Strategy is to achieve the maximum output or the best benefit while achieving sustainable gains. Consider the optimal fishing strategy for catfish: Suppose this fish is divided into four age groups, known as 1-age fish, 2-age fish, 3-age fish, 4-age fish. The average qualit

Note: This method is the optimal solution, and other fuel filling methods cannot meet the requirements. 2. A building has 100 floors. You have two identical glass beads in your hand. When you throw the glass beads down a layer, there will be two results: the glass beads are broken or not broken. This building has a critic

Looking for the optimal calculation method to find the optimal calculation array method, we can't figure out that I have two arrays: PHPcode $ arr1array (array (id gt; 1, pos gt; 1), array (id gt; 2, pos gt; 2), find the optimal calculation method Looking for the optimal array calculation method cannot be achieved.

method is applicable to the condition that n workpieces are processed by two or three devices (finite equipment), and all workpieces are processed in the same order on the limited equipment.Learning effect factor: In fact, practice makes perfect, the processing time will become less. For example, the nth part that is machined on this machine becomes t* (n) ^ (-a), where T is the original time, and a is the learning factor.The main references are: manufacturing operations Planning and controlWri

cluster center, WJ represents the average distance from all samples in class CI to the class CJ Center, and CIJ represents the distance between the class CI and the CJ Center. As you can see, the smaller the DB, the lower the similarity between classes and classes, which corresponds to the better clustering results. The process of determining the optimal number of clusters is generally the following: Given the range of K [Kmin,kmax], the data set usi

A * algorithm can be used for pathfinding of a single unit. However, in practical applications, multiple units are often moved at the same time, and they will affect each other and hinder the movement of each other. So once the conflict, the path calculated for each unit will be invalidated.A popular solution is to recalculate the path when a conflict is found. There are regular recalculation and so on. These are dynamic adjustment schemes, and the resulting paths are not

Many sorting methods have been discussed before Optimal Sorting. Is there any optimal method? Is there any way to sort the data as quickly as possible? The answer is clearly no. What is the best? A sorting algorithm is affected by many factors. It can also be measured from many perspectives. Some may focus on the number of comparisons, and some may focus on the number of records moving, some of them focus o

We know that looking for a maximum number in a data set with a capacity of N, no matter what comparison algorithm is used, it should be at least n-1 times, even if it is sorted by a competition, it will be n-1 times, otherwise, you cannot guarantee the maximum number. So what is the minimum number of comparisons between the maximum number and the minimum number in a data set with a capacity of N?The Optimal Method for Finding the maximum and minimum n

There are n villages in different coordinates and heights. Now we need to supply water to all the villages, as long as there is a road between the two villages, The distance between the construction pipes is the Euclidean distance between the coordinates (like the Euclidean distance), and the cost is the elevation difference. Now, the solution is required to minimize the cost-to-distance ratio. Obviously, this question requires an optimal rate spannin
