So my action_space is box(low=-45,high=45). However PPO never chooses values above 3 or so. Is there a way to get it to sample from the entire action space?

When I create a ParametersVariation simulation, the main model does not run. All I see is the default UI with iterations completed and replication. My end goal (as with most people) is to have a model go through a certain number of replications, but nothing is even running. There is limited documentation available on this. Please advise.
This is how Parameters Variation is intended to work. If you're running 1000 runs and multiple replications with parallel runs, how can you see what's happening in Main in each?
Typically, the best way to benefit from such an experiment is to track the results of each run using elements from the Analysis palette or even better to export results to Excel or similar.
To be able to collect data, you need to write your code in Java actions fields with root. to access elements in main (or top-level agent).
Check the example below, where after each run a variable from main is added to a dataset in the Parameters Variation experiment. At the end of 100 runs for example, the dataset will have 100 values of the main variable, with 1 value for each run.
I'm building a Grafana dashboard with some Stat panels that show average, minimum, and maximum time values (see below) for specific fields in my database. I'm storing the data in seconds and setting the value's units to seconds after which the panel displays the time in weeks, days, hours, etc. For the sake of consistency, I would like everything to be shown in days but I haven't been able to find a way to force units for the output value. If it's possible to do this, could someone please point me to some docs, or something that could show me which configurations to make in my panels?
So far, I've tried (without success):
Configure each panel to use units of days
The result of this was that everything showed up in years, etc.
Configure each panel to create a new field by performing a binary calculation where I converted from seconds to days and then I updated the units to be days
The result was that the values were not changed at all -> instead of showing X days, or whatever, it just showed the value in seconds without the units. I'm not sure what I messed up there, but it didn’t change anything.
I found this link that discusses setting a time range for queries
This didn’t end up being useful for what I was trying to do because it was actually geared towards changing the query to a specific date range rather than the output.
I looked through the transformations documentation, stat panel documentation, and a few other panel documentation pages in an effort to see if there was any information on how to do it but I was unable to find anything on forcing the output value to use a specific unit.
Edit:
So I kept messing around with the dashboard and got a solution that works - i.e. it's a "good-enough" solution (see below) - but, now, I'm curious if it's possible to show the units along with the value without it converting it to some other unit. Does anyone have any ideas about this?
One thing to note is that the data for this image is different than the data for the previous one so I'm expecting an inexact conversion to days.
You can use a custom unit. It is a bit tricky to enter the unit in the UI because of the automatic selection but if you enter i.e. "days" (without the quotes) in the Unit field ans instead of leving the field with tab or mouse click use the scrollbar of the combobox and select the last entry "Custom Unit: days".
Hope it helps. And for the record: I am using Garafana 7.1.4
I have an InfluxDB database with only x11 data points in it. These data are not displaying correctly (or at least as I would expect) in Grafana when the time between them is shorter than 1ms.
If I insert data points 1 ms apart, then everything works as expected and I see all x11 points at the correct times, as shown below.:
However, if I delete these points and upload new ones but this time one point per 100 μs, then although the data displays correctly in InfluxDB, in Grafana I see only two points in my graph:
It seems like the data is being rounded/binned to the nearest millisecond, an that this is related to the “precision=ms” setting in the query here:
but I cannot find any way to change this setting. What is the correct way to fix this?
You can't configure Grafana to support different time precision for the InfluxDB. It is hardcoded in the source code: https://github.com/grafana/grafana/blob/36fd746c5df1438f27aa33fc74b24be77debc7ff/public/app/plugins/datasource/influxdb/datasource.ts#L364 (It may need to be fixed in multiple places of the source, not only in this one.)
So the correct way to fix it is to code it, which is of course not in the scope of this question.
In Anylogic 8.5.1, I am doing a simulation for library evacuation, I have set and agent with Option-list that contains different types of users: students, organizers, graduates, and others. Also, I have set 'custom distribution' parameter to set the distribution values for each user. Until now, I have run the model and every thing is working well.
What I want is:
1. to use 'pedFlowStatistics' line in particular places (I can do this);
2. want to count the users that pass this line (I do not know how to do it);
3. then draw a chart to highlight the different number of users that passes that particular line space (I do not know how to do it).
I need help in the above situation, thanks in advance.
I do not have a Java background.
It's not possible to count based on conditions with pedFlowStatistics... you can only count the total pedestrians using:
pedFlowStatistics.countPeds(); // counts total number of pedestrians
pedFlowStatistics.traffic(); //shows the number of pedestrians per hour
You can use these functions directly in your chart.
But since you want to count based on conditions (the type of user they are), you will need to be smart about this and depending on your model, you will have to count pedestrians in a different place... or maybe use 2 ped go to blocks and count in between... it depends on your layout and model.
I am trying to reduce the throughput to 3 rows/s. I tried searching for this online but didn't find much. Can anybody help?
My current job looks like this:
Or is it possible to limit tHTTPRequests in the component?
For this you will want to use the tSleep component that will introduce a wait time per row.
The wait time is in seconds but you might be able to use a floating point value (eg. 0.3333). Otherwise you'll be limited to 1 row/s.
If you can't use a floating point value in the tSleep configuration and you absolutely need 3 rows per second then you could use a tJavaRow component that passes everything in the input to the output but also uses this snippet of Java code:
Thread.sleep(333);
This will sleep the running thread for 333 milliseconds on each row of data being passed through the component and give you roughly 3 rows per second (minus actual processing time which in this case should be minimal).
