Problem one: Only the flight-gate assignment is considered. As the first step in analyzing the impact of the new satellite office on flights, first set up a mathematical optimization model to allocate as many flights as po
training set is to think of ways to get the most out of a set of parameters. It is advisable to take the logarithm of probability to make the equation linearized.OK, so far, the expression of the derivative of each parameter has been calculated, F_j (x, y) is very easy to find, for any training set this is known. And the later E is more troublesome, it needs to bring all the feasible tags into the FJ, and Times p (here p also, given wj,p is known) but this kind of gradient calculation is very l
Article Description: Product Interaction Design Example: The airport cigarette smoke device.
The smoking room in the capital airport does not put a few fixed lighters like other airports, but cigarette smoke device, and car smoke device is basically the same: first press the heating, after heating, it will automatically bounce, pull out, the inside of the resistance wire is red, you can point to

For some airports, K airports must be selected to minimize the maximum number of airports from other airports.

At on the afternoon of October 30, at the invitation of Guangzhou guanglianda company, the company participated in the cost management software application (GCM) of the "Expansion Project of the fourth Bureau of construction of Baiyun Airport" organized by the company. Many units in Guangzhou participated in the activity, mainly for housing construction systems, road construction units only support us.
The project is located on the right side of the
Finally, I can sit and use my own book to access the Internet.This is the fourth time that I have been to Changi Airport. These four times are all for access to Jakarta, so I want to transfer the traffic here. The hardware and software of Changi Airport are good. From the IT aspect, there are both free PC and free laptop acess. The former must stand on the Internet, and there are many restrictions such as t
Question:
There are two runways, W and E. Each runway is numbered from 0 at each time, and each time there are WI and EI planes arriving at these two runways. In addition, only one plane on the runway can take off at each time. Ask how to minimize the maximum number of aircraft. (The number is calculated at each time point before the plane departs)
Ideas:
It is also the smallest problem of the maximum value. Binary can be used, but I didn't think of binary.

Question:
There are N points on the plane. Find a straight line so that all points are on the same side of the straight line. And find the minimum value of the distance between these points and the straight line.
Analysis:
As long as the straight line does not pass through the convex hull, the first condition is met. To minimize the distance and distance, the straight line must be on the side of the convex hull. After finding the convex hull, enumerat

The shortest path.
Run Dijkstra once from the start point and the end point to get the distance from the start point to any point. Enumerate the commercial lines used to find the optimal solution.
When the problem-breaking card is output, it seems that it is more difficult to record the predecessor and output than the algorithm itself.

. If someone, like the old man, directly accesses company emails through OWA, the information is enough to break into the internal network of a company. If you need to access personal or sensitive information on any public computer, such as your personal email, pay attention to the following two points:
Do you trust the provider of this computer.
Do you trust the security configuration of this computer.
If any condition cannot be met, you should not proceed. For example, for a machine in
