solutions. The topic is a bit running, and now the scheme of trimming is to trim the alarm of some emails and text messages while I am developing the alarm platform Phase II. The scheme of trimming is within 3 minutes, if duplicate information is not sent, you can define the trim time for each information type on the platform. Some serious and disaster-level alarms need to be contacted by NOC. At this time, we can use some voice alarm API interfaces to solve such problems. Most of them use twil

Zookeeper Vulnerability Analysis For those who do not know ZooKeeper, it is a well-known open-source project that supports highly Reliable Distributed Coordination. It is trusted by many security companies around the world, including PagerDuty. It provides highly available and linear services based on the leader's philosophy, and these services can be dynamically reselected by most arbitration to ensure service consistency. The leadership election and

Online a bunch of people to write km algorithm, have not found out which speak better.KM algorithm approximate process:(1) Initializes an LX array to the one of the boy's most weighted edges. Initialize the LY array to 0.(2) For each boy, find a Girl object with DFS, record the S and T sets on the way, and update the slack value for each girl. If the object cannot be found, go to 3.(3) Finding the minimum slack
HDU_1853 First, if you want to ensure that a graph has a ring and there is no intersection between the rings, the outbound and inbound degrees of each vertex must be 1. Therefore, we can split a vertex into two vertices, represent the degree of exit and inbound respectively, and then find the perfect match of the Bipartite Graph after the split point. I have come up with two ideas on how to determine whether the source image can constitute a perfect match: ① Before using the KM algorithm, use
clock. 4.Input to Output Path The design can has a combinational path going from an input port to an output port. This path can is constrained and timed just like the input andOutput paths we saw earlier. Figure 8-7 shows an example of such a path. Virtual clocks is used to specify constraints on both input and outputPorts. Here is the input and output delay specifications.Set_input_delay-clock virtual_clkm \-max 3.6 [Get_ports INB]Set_output_delay-clock virtual_clkm \-max 5.8 [Get_p
KM algorithm can be achieved o (n3). We give each y vertex a "slack" function slack, which is initialized to infinity each time we start looking for an augmented path. While looking for an augmented path, when checking for edges (i,j), if it is not in the equal sub-graph, let slack[j] be the smaller value of the original value and a[i]+b[j]-w[i,j]. This way, whe
this layer. Of course, although we have excellent process management tools such as pm2 to help us, we will automatically restart the service after it crashes... But we need to get the error message immediately .... Even if an exception is retained in the errpr. log of pm2, who will be able to stare at the error log. To solve this problem, I wrote a piece of code to collect error logs, hoping to help you. Var pm2 = require ('pm2'); var Slack = require
modification, in this way, the complexity of modifying the top mark is O (n ^ 2), and the total complexity is O (n ^ 4. For each element YJ of not t, define the relaxation variable slack (YJ) = min {L (xi) + L (YJ)-W (XI, YJ ), | XI in S}, it is obvious that Delta = min {slack (YJ), | YJ in not t} each time, O (N ^ 2) is used after each expansion) the calculation of the time is a bit of the initial

Support Vector machines is an optimization problem. They is attempting to find a hyperplane that divides the both classes with the largest margin. The support vectors is the points which fall within this margin. It's easiest to understand if your build it up from simple to more complex.Support vector machine is an optimization problem. They (these points) attempt to find a hyper plane at a maximum distance (2/| | w| | ) to divide two classes. Support vectors are those points that fall on the edg
