I tried Method 2, the adding dummies approach, and find the all the dummy activities are placed at the end of the initial order. Wouldn't it make it very difficult to place those dummy to honor the constraints? If this dummy approach is to work, they would need to be considered as a group with the rest of the activities in that group, am I right?

Would it be max 6 days, or 7 days as you said, for the dummies to avoid them being on first and last day
Wouldn't max 7 days allow this: x 2 3 4 5 6 7 x

Asking the community for advice on how the best spread a number of activities over an 8 days cycle:
7: just 1 day min apart
6:
Method 1:
-- Take the last 4 activities as a group, add a 2 days min day constraint to the group
-- All 6 has a 1 day min days constraint
-- All 6 has a 6 days max days constraint (to avoid the first and last activities being back-to-back in the cycle
Method 2:
-- Add two dummy activities the make it a group of 8
-- Add 1 day min days for the group of 8
-- add 2 days min days for the dummy, to avoid the dummy (free day) being back to back

5:
Method 1: same as 6
Method 2: same as 6, just three dummies added

4: 2 days min day for the group, 6 days max day

3:
-- a1 and a3 min 5 days apart, max 6 days apart
-- a1,a2,a3 min 2 days apart, max 3 days apart (I think this will ensure that there will never be 3 consecutive free days)

My main question is, is method 1 or method 2 for the >5 cases more efficient for FET?

Or any other ideas?

Thanks.

Tested:
A room max tag per day
A room max tag in per week
All room tax tag per day

All work.

Thanks!

Liviu, can you compile a Windows version for me to check? I am primmarily using Macs (M4 is so fast!), but I can test on Windows.

When the activity tag is changed, the same activity tag used in constraints in this category doesn't get updated, leads to an error. May have similar problem with similar constraints, I have only used the max tag for a week.

Michael,

Thank you! The download worked. In your website, you mentioned about "collaboration", is it the "Share Screen" option under "Help"?

Collaboration is actually one of the reason why I want to explore PlanXY. I wish there is a way that my collegue and I can edit the same file an not over writing each other's work. Is it something that PlanXY support?

Hi Michael,

I've been using FET for 15 years, just love it. Really want to download and try your tool, but I am having problem with the download from the Microsoft store. Keep saying it is have some error. Any idea?

Looking forward to try your tool!

OK, as far as helping with the performance, not as well as I've hoped. The problem is I am adding extra "free" hours to patch up the holes so I can use this "max single gap" constraint to avoid a certain layout. In the example of a 9 hours/slots afternoon, here is another case I want to avoid:
Recap: In a 9 slots afternoon, 3+3+3 is good, 4+4 is ok. 3+5 is NOT good, 3+4 is also NOT good.

With the "max single gap" constraints, I cannot really avoid the 3+4 case since there are two open slots between 3 & 4 out of 9. I tried to get it to work by adding an extra "free hour", so to avoid a single gap would achieve what I want. The problem is, there is no exact way to add the free hour at the right place.

So, I think it would be great if we can "adjust" this "single gap". By default, it is just one hour. Is it possible to "adjust" the gap to be other number of hours? So I can avoid any kinds of gap.

*** by the way, I meant to add this whole conversation to the thread that I posted earlier that resulted in this new feature. I did a search on the forum, saw the word "gap"... thinking that this was the right thread. I just realized my mistake.***

It works! Now I need to verify that my trick actually helps with the optimization. But as far as the functionality of avoiding gap, it works!

It is ready: https://lalescu.ro/liviu/fet/download/custom/yushB/

Please check that src/engine/generate.cpp contains the string "Yush" twice.

Yup, got it. Actually has the string "Yush" three times. Will let you know if the result.

OK. Qt all set up. Ready to compile.

I am sure Darren would like to help us if you run into a problem.

I think I will need his help. Downloading Qt, it says it's going take over 1 day to finish the download!

OK, I will try now and let you know soon.

Thanks! Downloading and installing Qt for Mac and Xcode!
