### Re: JExocet Pattern Defintion

David P Bird Wrote:
But the strong derived inference will only hold when the box 2 target is in r2, as then r1c78 must contain the two true base digits. Therefore it seems a distinction must be made between be JEs with co-linear targets and those with diagonal ones when this inference is used.

I agree that this move is subject to the same caveats as Exocet secondary equivalences generally. The two Targets cell must be in
different rows and the opposite Target cell must not be capable of holding a non-base digit, as it might do in the case of twin Exocets
where there is a SIS between two target cells in the same box.

Nevertheless it applies equally to r1c8 and r1c9 (in your example). In other words if both cells held other non-base digits (other than the SIS digit 4)
they could be eliminated from both cells. I've never noticed this before, perhaps it's quite rare if an Exocet that hasn't been partially dismantled by
other moves. In your example, without the SK loop eliminations there are more than 2 4's in Box 3.

This is the second second post summarizing results on the sample test made in the grey/green areas.

At that point the question is what to share and how to do it.

### Re: JExocet Pattern Defintion

Sorry guys but this will be a series of holding answers as my free time has been rather overwhelmed of late.

Champagne, Many thanks for the efforts you've made, I'm sorry I haven't had time to sample your latest puzzle sets which I need to do to properly understand how you've organised them, before I answer you.

If you have nothing better to do in the meantime, I'd be interested in finding out how common Junior Exocets are with both targets in the same box, and how common Advanced Exocets are. Otherwise I suggest you take a break until I catch up. I'll try to do that by tomorrow night.

Blue, I've spent some time considering your example and wondering if you were envisaging some procedure to follow when a near miss JExocet has been found. Is that what you were trying to suggest?

Leren If the first thing we do when we find a JExocet is to eliminate the non-base digits in the target cells I'm not sure that some of the scenarios you discuss are possible. However Champagne has mentioned double JE3s which I haven't considered of late (and have no memory of considering them 10 months ago) so I could be wrong.

All (past and present), I take it from the silence that the suggested partition between Junior & Advanced Exocets is worth running with at least for the time being. JExocet has been, and continues to be, a team effort and I just feel I'm doing the housekeeping.

Hi David,

I don't know what I'm trying to suggest -- if anything. I don't exactly know what you look for to spot them, other than that it has to do with what clues are and aren't present, and where. My thought was that with only one clue "out of place" in the example, when compared with a normal JExocet, it might not be that difficult to extend your ideas (whatever they might be) to be able to recognize the other kinds of patterns too.

Regards,
Blue.

Maybe we should have spent more time on the topic of technique hierarchy. Then these puzzles might not have been included in the first ten puzzles in one of champagne's recent lists for JExocets.

Yes. Actually I would also consider the following partitions (within the JExocet family):
- non-degenerated vs degenerated
- standard vs Franken

Can you give one more result: the proportions of JE3 and JE4 in your whole list, each as a function of the number of clues?

### Re: JExocet Pattern Defintion

just for information, I loaded the file of "not common" puzzles
here

Again,the classification just refers to the way my solver sees them. Some of them can be seen as very common by others.

Most often, we have

- a mix of JE2 and JE3
- more than 2 JEs

### Re: JExocet Pattern Defintion

Hi Champagne

Sampling your puzzle collections I'm having problems with many of them recognising the JExocets your program has found. I suspect this is because it's reporting those where a given in the JE band is included in the base set. Is that right?

If so, how easy would it be for you to either
a) to screen these out
or
b) to screen out those with no eliminations in the target cells?

The JExocet signature pattern isn't that uncommon and will regularly appear in reduced cells in the easier puzzles. However I believe that in these circumstances only rarely will they be of any use.

It would take me ages to do this manually

we have here 2 different issues

The first one, somehow purely academic in the green area is " can we find the JE pattern with lower ratings"
The second one is "is the JE pattern a solving tool in these areas"

No doubt that in the green area, limited by construction to a SER rating 0f 7.5 (not more than classical XY chains), it has nearly no chance to be of any interest as solving tool.

In the grey area, SER ratings go form 7.5 to 10.8 (could be exceptionally more if I generated puzzles eligible to potential hardest but not yet in the data base)

Drawing conclusion on the potential interest of the exocets found as solving tool would likely require a split of the grey area in several sub areas.

Back to the first question " can we find the JE pattern with lower ratings".

Even here, I have several questions looking at the raw results.

One example: what is the meaning of a double 3 digit exocet.
I had a first look in the corresponding file in the green area and found highly downgraded patterns of small interest (if any). This meet some later remarks from David (I'll answer to that in a separate post).

I am preparing a run with no elimination at the start and I am expecting significantly different results, especially in the green area.

I can surely do an analysis by number of clues. Seen the size of the files, this requires a specific code, so the answer in not for to-day.

EDIT
what I can easily do is a split using the original count of clues;
This is not at all the count at the moment the exocet was found, especially in the green area.

I defined grey zone with SER between 9.0 and 10.5. These were fuzzy values, but extending them overly makes it meaningless.

That's what I meant: #clues in the puzzle before any solving
