I made an email inquiry to Dynaxys, but that has gone unanswered.Ah, succession. That topic has come up often enough to get its own topic in the FAQ. The short answer is that Dynaxys has agreed to keep ORP running as long as possible, which means they will keep the server running and update the personal income tax table once a year. One or two conditions will being ORP to its end:
ORP is propriety in the sense that I actively defend the copyrights, but it is not secret. I will answer any question asked. ORP is documented only in the sense that the code is the documentation. Alas, nothing else. ORP is my play ground where I explore what can be done with the LP paradigm. And I console myself that it may be serving some sort of a social good.
- Microsoft changes its operating system in such a manner as to stop running ORP's 30 year old code, namely the matrix description and the optimizer.
- The US Congress changes the tax law.
i-orp has been returning a page "The Optimal Retirement Planner is offline" for quite some time. Has anyone been in contact with James lately? In the past he's replied to mail on orplanner, but a note in February went unanswered. I didn't think much about it, but a more recent one also went unanswered. I found a resume (cached), but it's from 2015 https://webcache.googleusercontent.com/ ... clnk&gl=us
i-orp was my go-to for comparing various approaches to pull from various accounts in retirement. I hope it's not gone for good.
Here's a bit from Jim, back in 2019:

I read that due to age and health, the I-orp author is unlikely to be able to support it anymore.
Sengsational may be thinking of a poster at Bogleheads, who made a spreadsheet that uses a freeware GNU solver for the LP engine. Here's a link to a thread where he discussed it:
https://www.bogleheads.org/forum/viewtopic.php?t=365518
I tried an early version of the spreadsheet solver a couple years ago and couldn't get it to solve, maybe it's debugged now, but I haven't checked.
I'm not sure about James, but I'm still around, just on extended travel until recently.Speaking of sengsational, glad to see him back. I was afraid he had gone the way of the i-ORP guy. Seng was on yesterday and posted elsewhere, not this thread.
I-orp is back on-line!
Broke again?
I ran this a couple time after the 11/23 back on-line post (successfully). Now the data entry pages are there, but trying to run it results in a proxy error.
Anyone able to run it?
Yep, now it is working. Thanks.I just ran it today and it seemed to be working fine.
