Search engine one. What is a robots.txt file? Search engine through a program robot (also known as Spider), automatic access to Web pages on the Internet and get web information. You can create a plain text file robots.txt in your Web site, in which you declare the part of the site that you do not want to be robot, so that some or all of the content of the site is not included in the search engine, or the specified search engine contains only the specified content. two. Where is the robots.t

Disable page cache: Meta is an auxiliary tag in the head area of the html language. Maybe you think the code is dispensable. In fact, if you can make good use of the meta tag, it will bring you unexpected results. The meta tag has the following functions: Search Engine Optimization (SEO), defining the language of the page, automatically refresh and refer to the new page to achieve the dynamic effect of page conversion, control page buffering, page Rating Evaluation, control page display win

symmetric; Butterfly "Foot" section, this section of the page is displayed as a link from the left to other pages, or from the left or right to link directly to the right, and a small part of the middle, left or right, there is no link, on this part of the page, regardless of the use of forward traversal or reverse traversal can only traverse to a limited number of pages.After the above analysis, we can conclude that the crawler should start from the left part of the butterfly type as far as po

requests. Therefore, the first solution is to submit record requests asynchronously through ajax after page loading, the result is invalid. Experiments show that this method is only valid for low-level robots; Solution 2: Determine the width or height of the requested client browser window (invalid) It can be inferred from solution 1 that these traffic software does not simply simulate http requests, that is, requests through real browsers, but while

Question: HDU 4003 find Metal Mineral N mining plants are found on Mars. K robots start to mine from s point, and cost between road sections is given to obtain all the mines at the minimum cost. Category: tree-like DP + group backpack Analysis: Conclusion 1: If we start from point I, K robots will return to point I after collecting all the mines with K as the root node, the cost is the sum of the cost of

Collision avoidance is a basic topic in robot navigation, game AI, and other fields. Many algorithms have been proposed for decades. Note that this mainly refers to the local Collision Avoidance algorithm. Although it is closely related to the Global Path Planning Algorithm (A * algorithm, however, there are still some differences (partial collision avoidance algorithms mainly focus on the upcoming collision, while path planning mainly focuses on determining the optimal path to the destination i

the robots created by others drop it out and then designed my own strategy. At that time, the main challenge was a kind of robot called seesaw bot, which would move back and forth and would be hard to hit. Cleaner encountered a lot of trouble when trying to hit them. My solution? I used 1.3 cents of knowledge to estimate the angle of seesaw and then shot at that angle. I completed the preparation with a sigh of relief, and then watched cleaner 3 clim
