### Exercise 3: understand and visualize Batsim outputs
Simulation outputs are stored in the `out` directory.
You have [schedule-centric outputs](https://batsim.readthedocs.io/en/latest/output-schedule.html)(`schedule.csv`) and [job-centric outputs](https://batsim.readthedocs.io/en/latest/output-jobs.html).
Open them, read the doc, and make sure you understand most of the fields.

Finally, to get a visual representation of the outputs, we will use the visualization software `evalys`.
We provide a wrapper of `evalys` with the main functions that you need in the file `util/plot.py`.
The `jobs.csv` output that was produced before is not suitable for visualization since it has no jobs that executed.
Produce the visualization:
Visualize the jobs on the example instead:
```bash
python util/plot.py out/example_jobs.csv
```
You have an option to store the output in a PDF file.
NB: the script has an option to store the output in a PDF file.
Check available options with `python util/plot.py -h`.
### Exercise 3: FCFS monomachine
Now, it's time to develop your own scheduler!
We will start with a FCFS monomachine: it schedules the jobs by order of arrival (and lexicographical order on the job ID in case of a tie).
### Exercise 4: FCFS monomachine
Now, it's time to develop your own scheduler.
We will start with a FCFS monomachine: it schedules the jobs by order of arrival.
Create a file `fcfsMono.py` in `sched` directory.
Create a file `fcfsMono.py` in the `sched` directory.
Draw inspiration from the template in `sched/template.py` to create your scheduler.
Warning: the file name and class name must match (for example, `fcfsMono.py` for the file name and `FcfsMono` for the class name).
Test it on `2jobs.json` and `ex1.json` inputs, and other inputs that you will create.
Visualize the outputs with evalys to see if it worked correcty.
You can use the following functions:
-`job.id`, `job.submit_time`, `job.profile.name`, `job.requested_resources`, etc. to retrieve information about the job
-`self.bs.reject_jobs(list_of_jobs)`: to reject all the jobs in the list `list_of_jobs` (message [REJECT_JOB](https://batsim.readthedocs.io/en/latest/protocol.html#reject-job) in Batsim protocol)
-`self.bs.execute_jobs(list_of_jobs)`: to execute all the jobs in the list `list_of_jobs` (message [EXECUTE_JOB](https://batsim.readthedocs.io/en/latest/protocol.html#execute-job) in Batsim protocol). **Warning:** this function expects the jobs to have been allocated to one or several machines first. Use `job.allocation = 0` in the monocore context.
Test your algorithm on `2jobs.json` and `ex1.json` inputs, and other inputs that you will create.
Visualize the outputs with the visualization script to see if it worked correctly.

- implement another monomachine scheduler: EDF
- compare FCFS and EDF in terms of mean waiting time and tardiness
