DescriptionAssume the coasting is a infinite straight line. Side of coasting, sea in the other. Each of small island was a point locating in the sea side. and any radar installation, locating on the coasting, can only cover D-distance, so a island in the sea can is covered by A RADIUS installation, if the distance between them is at most d.We use Cartesian coordinate system, defining the coasting is the x-axis. The sea side is above x-axis, and the la

[Description ]: Given n small islands and their locations, and entering the radar radiation area, how many radar stations are required to cover all small islands? [Train of Thought Analysis ]: The first thing that comes to mind in this question is the use of greedy algorithms, but how can we get greedy? When I started to solve this problem, I had only one idea: to make every

There is a path, and the two sides can be imagined as Y = 0 and y = 1. Now we will give you a list of radar, where each radar is (x coordinate, Y coordinate, and radiation radius ). Ask if a car can pass this road. Code statement: 1 static class Radar { 2 double x; 3 double y; 4 double r; 5 public

Topic linksFor M radar, N cities, and the coordinates of each city, the M radar can only use K, and the minimum radius is obtained under the condition that the K radar surrounds all cities.First to find out the distance of each radar to all cities, and then the two-radius, if the distance is less than two points, add t

Main topic:Suppose there is an infinitely long coastline with N islands above the coastline. There are radars on the coastline, each radar can detect a circle with a radius of R, and the island can be detected by radar only when the distance between an island and the radar is less than or equal to R. gives the coordinates of all islands and the radius of the

Unconsciously this spring festival has been over, sorry that the family did not have a network, not in time to send blessings to everyone, today back to Shenzhen, tomorrow will work, small partners are not like me? Today is about a lot of people have seen the animation, radar search friends, the principle is very simple, you read my analysis, it will feel very simple, international practice, no picture no truth, we first look at the effect of the pict

The main topic: There are N islands in the sea, now want to install radar on the coastline to detect these islands (the coastline is equivalent to the x axis, the island is above the x-axis), the radar detection range is a radius d circle, known N Island coordinates, ask you at least how much radar to detect all the islands If the entire island cannot be detected

With the development of technology and the reduction of cost, the field of robot, unmanned aerial vehicle and unmanned driving has become an important application field of LiDAR in the field of laser radar. There are many kinds of sensors in the field of robotics, including cameras, lidar, millimeter-wave radar, ultrasound, infrared and many other sensors. The features and advantages of each sensor are not

Last spring Festival when Alipay implementation of the collection of Fuwa activities really can not fire, but also to the Spring Festival Gala can be a national participation in a set of Fuwa activities, set Zie can be divided into two billion large red envelopes, but unfortunately no dedicated fu ... At the time at home there was nothing to write a swish plug, as long as a swish of the time point of the plug-in can be automatically clicked on the click of a thump to the red envelopes, just pure

The boss wants to draw a radar chart, but what about the data groups? Not a point of Excel to draw it, then you can use Python for batch production, get the style as follows:First make a demo of Excel, scoring for Excel random number generation:1 =int ((RAND () +4) *10)/10Add tags, etc. to get the Excel style as follows (part, total 32 lines):Then the next step is to open the Python code, this article is based on python3.4 to write1 WB = Load_workbook

The reason why we put the details and user experience together is that the two are so inseparable. The so-called "Details determine success or failure", in terms of details, allows users to feel convenient, comfortable, not painstaking and warm, more humanistic ideas, more feelings, the products made are naturally more popular than other rigid products. Today, we will evaluate the performance of the two popular dictionaries, youdao dictionary and Bing
