Hello,
More of my philosophy about the analytic queueing-circuit analyzer PDQ
and more of my thoughts..
I am a white arab from Morocco, and i think i am smart since i have also invented many scalable algorithms and algorithms..
I think i am highly smart, since i have also passed two certified IQ
tests and i have scored above 115 IQ, so as you have just noticed i have
just talked about timesharing and coroutines in the following link:
https://groups.google.com/g/alt.culture.morocco/c/tN_O-AgkGjY
And i have just talked about Markov chains in mathematics and about
Petri Nets here:
https://groups.google.com/g/soc.culture.quebec/c/LPE4zR-BqHY
I now i will talk about my PDQ for Delphi and Freepascal:
This is a port by Amine Moulay Ramdane of PDQ version 6.2.0 to Delphi
on Windows and to Freepascal on both Windows and Linux, i have also
provided you with two demos, one queuing MM1 demo, and another Jackson
network demo. Also i have provided you with my HTML tutorial on how to
solve analytically the Jackson network problem provided to you as a PDQ
demo.
PDQ is an analytic queueing-circuit analyzer made freely available under MIT/X11 license from:
http://www.perfdynamics.com/Tools/PDQ.html
You can download it from my website here:
https://sites.google.com/site/scalable68/pdq-for-delphi-and-freepascal
And here is an example in Delphi and Freepascal of the Jackson network
demo that i have included inside the zip file(and you can look
at my mathematical modeling of it here in my website:
https://sites.google.com/site/scalable68/jackson-network-problem):
