The number of tasks included in the service portfolio is 4; Each task corresponds to 1000 cloud services with the same functional attributes and different non-functional attributes; By default, the output of the first task is the input of the second task, the output of the second task is the input of the third task, and so on; The non-functional properties of each service consist of five: execution price (The range is: [0,100] RMB), execution time (The range is: [20,200] ms), probability of success (The range is: [0,1]), availability (The range is: [0,1]), reputation(The range is: [0,10]); Each dimension attribute of cloud service needs to be normalized; Calculation formula for quality of service: execution price ∑ execution time ∑ probability of success ∏ availability ∏ reputation Average The input is a quadruple (i, j, k, c), and the output is the QoS value of the combined service, That is, four cloud services are composited: the i-th service in the first service library, the j-th service in the second service library, the k-th service in the third service library, and the c-th service in the fourth service library.

这是一个关于云服务组合的问题,根据提供的信息,可以计算出组合服务的质量。输入是一个四元组(i, j, k, c),输出是组合服务的QoS值。每个任务包含100个云服务,每个服务有不同的非功能属性,需要进行归一化处理。计算QoS值的公式包括执行价格、执行时间、成功概率、可用性和声誉等五个维度。

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
This message is usually displayed when a Gradle build fails, and it's suggesting you to run the build again with some additional options to get more information about the failure.
Here's what the options mean:
- `--stacktrace`: This option will print the full stack trace of the error, which can help you identify the root cause of the problem.
- `--info`: This option will print more detailed information about the build process, including the dependencies being resolved and the tasks being executed.
- `--debug`: This option will print even more detailed information about the build process, including the values of all the variables and properties used in the build.
To use any of these options, you need to run the build command again with the desired option. For example:
```
./gradlew build --stacktrace
```
I hope this helps! Let me know if you have any more questions.
Task watchdog got triggered. The following tasks/users did not reset the watchdog in time:
这个问题通常是由于任务或用户未及时重置任务监视器而导致的。任务监视器是一种机制,用于检测系统中的任务是否处于活动状态。如果任务监视器检测到任务或用户未能及时重置任务监视器,则会触发任务监视器,并可能导致系统意外崩溃或重启。
要解决这个问题,您可以尝试以下步骤:
1. 检查系统中是否有任何长时间运行的任务或进程,并尝试优化它们的性能,以减少它们对系统资源的占用。
2. 检查系统中是否有任何异常或错误,例如内存泄漏或磁盘空间不足等,这些问题可能会导致任务监视器触发。
3. 确保您的系统和所有驱动程序都是最新版本,并尝试更新它们以解决任何已知的问题。
4. 如果您无法解决这个问题,您可能需要联系系统管理员或技术支持人员以获取帮助。
