Eliminate lines from consecutive pairs of draws.

Eliminate lines from consecutive pairs of draws.

Postby pyst7lot » Mon Jul 26, 2021 12:50 am

Have just discovered that the last 10 draws in our NZ Lottery have not appeared in any consecutive pair of previous draws - the 11th failed once. If there were no repeat numbers in any pair of consecutive draws that would be 1.8 million combinations (2080 draws) which I would be happy to eliminate. That's 12 boxed numbers (928 lines) x 2080 draws. Is there an easy way to do this? I can only see using number groups as a way to do it - can I have 2080 number groups? Repeat numbers will reduce that number but it will still be a very large set of combination to remove. :)

Edit: Also see that the non-appearance of any 4 numbers appearing in recent consecutive pairs of draws is worth looking at.

Can you give a ticket(s) example? I'm trying to understand what is meant by "consecutive pairs of draws" and "12 boxed numbers".

These are our last few draws for NZ Lotto.
2083: 29 28 5 38 7 33
2084: 7 9 24 35 10 14
2085: 8 9 30 10 6 20
2086: 34 8 40 29 6 23
2087: 30 13 28 33 26 39

I want to eliminate all lines of six numbers from draws 2083 & 2084, 2084 & 2085, 2085 & 2086 etc.

Draws 2083 and 2084 have 11 unique numbers and I want to eliminate any lines which have all their numbers in those 11 numbers.
Draws 2086 and 2987 have 12 unique numbers and I want to do the same with them and all other consecutive pairs of draws.

I actually changed the 2087 draw - the 33 should be 34 but it didn't suit my example.

Boxing numbers is like wheeling a full wheel - like this software does.

I hope that's clearer than mud. :)

Edit: What I want to do is the same as what this software already does with individual past draws with the Match Winning Numbers filter.

Yes, that's 'Match Winning Numbers' with 2 latest draws. The filter can also take it a step further. You can also have a Min/Max ticket count for each match. 8)

No, that's only eliminating numbers from each draw. I want to eliminate numbers which appear in pairs of draws.ie any line which has 3 numbers in one draw and 3 different numbers in the next draw.

To clarify,...Draws 2083 & 2084(consecutive draws) numbers are; 29,28,05,38,07,33 & 07,09,24,35,10,14 <-- So any combination of these two draws numbers to make a line/ticket, then reject it? In other words, combine two consecutive draws into one by their numbers(like a number grouping), then filter. If so, I might have a complex filter setup that would work.

Yes, I was looking at using number groups in a complex filter BUT that's 2088 number groups that I have to look forward to making. Will the software allow that many number group filters?

Hi pyst7lot,
Since lottery draws are random and have no memory of previous draws, you could get similar results by using "Match Numbers in File" from the basic filters and
using a file of say 2080 random 11 number combinations from a field of 40 numbers and set "Reject" "Match 6".
You could get the file in stages from random.org or generate it in Expert lotto.

The number groups have a limit of 99 groups in program, and you have to be careful depending on the groups setup. To many large groups may slow down or cause EL to not respond(memory, resources etc.).

The complex filters I tested partially work for consecutive pairs combinations as long as there is no repeats. However, after much testing, there isn't an automatic way to merge and filter two consecutive draws numbers. So I would use something similar to what ->daniel suggests, and create a file to match numbers from, maybe by merging the database in a spreadsheet program(i.e. Excel).
----
Here's a sample of a complex filter setup I was testing;

Complex Filter Group(Min:2/Max:2 to pass) [Accept]
- Match Winning Numbers 3 (Latest draws 1 to 1) [Accept]
- Match Winning Numbers 3 (Latest draws 2 to 2) [Accept]

Then 'Run' with a full wheel package...

These are the first two draws in the winning numbers table.

5,7,28,29,33,38 <- The filter will look for 3 numbers from here...
7,9,10,14,24,35 <- and 3 numbers from here.

So ticket 1,5,7,9,10,28 is accepted and has 3 numbers from each. But as you will note, 7 was a repeat and the filter fills in the missing position with a 1.

As true as that may be I did testing on our most recent 20 draws and after doing what I suggested (using Excel) I had only one draw which wouldn't have been included in the combinations I would have had left. What I'm suggesting is only an extension to the Match Winning Numbers filter already available - are you saying that is a waste of time as well. :)

You could try reducing the combinations to 10 or 9 numbers and increasing the total combinations to 10,000.
Just a suggestion.
Have you seen Best Match Searcher3 at intelbet.somee.com?
You could use the files generated by this program in "Match Numbers in File"
filter in Expert Lotto

I did end up using the Match Numbers In File filter. Using Excel I created a file which had lines for every consecutive pair of draws except the last 10 draws. Set the filter to reject any combination which had a 6 Match. It reduced the usual 6/40 combinations of 38383830 to 2815343 - a 27% reduction. The latest 10 draws which weren't included in the 'file' were all in the accepted lines. It probably fails sometimes but it's looking like it's a worthwhile reduction the majority of the time. It needs to work 1 in 4 (approx) draws to break even and it succeeded in 19 of the 20 draws I checked it with.

Damn, it didn't work out as well as I had hoped. My Excel sheet was a bit wonky - I messed up the cell formulas - forgot to use some $s. However, I found something similar which works better using the number of 5 number matches in double sets of numbers. I didn't just use consecutive draws but also each draw pair with the one after next and again with each draw with 3 draws later ...and again with each draw with 4 draws later ...up to each draw with 14 draws later. Nothing scientific but it seems to work a good percentage of draws. Nothing I do is scientific - I'm not smart enough for that. lol I'm not a fan of filters which rely on expectation - things like 3odd 3even which should appear every 3rd draw but sometimes take 8 or more draws to occur.
