Hi,
</SPAN></SPAN>

Here I have a question how to reduce betting blokes that can guarantee max 1 incorrect, what I mean this, for example "Euromillions" playing 8 numbers direct we are playing 56 lines it cost 140€ "Formula=COMBIN(8,5)" if out of 8 numbers 5 numbers are correct we get the 1st price guarantee 100%.
</SPAN></SPAN>
But instead 8 numbers direct if played in reduction we play only 5 lines it cost 12.50€ but it guarantee only 4 numbers can be correct if numbers drawn any 5 out of played 8. So far 1 number less.
</SPAN></SPAN>

My question is about to play football reduction...it is difficult how do I explain it but here is my attempt...
</SPAN></SPAN>

Say for in example1 there are 2 teams the can have the end result in a 9 different ways as shown in the cells C6:D14...I can bet all 9 but as it is a money question I want to play less combinations but ensuring 1 must be correct out of any 9 results if I bet 3 lines as shown in the cells H6:I8 there is minimum 1 correct and 1 wrong.
</SPAN></SPAN>

Say for in example2 there are 3 teams the can have the end result in a 27 different ways as shown in the cells C6:E32...I can bet all 27 but as it is a money question I want to play less combinations but ensuring 1 must be correct out of any 27 results if I bet 6 lines as shown in the cells H6:J11 there is minimum 2 correct and one wrong.

The above result I have come up checking one by one it has took 2, 3 days to ensure.
</SPAN></SPAN>
And I guess they are right but not sure 100%
</SPAN></SPAN>

As the team increases lines increases...now I want to work out with 4 teams there would be 81 lines as per example3, is there any macro or VBA can extract only those lines out of 81 which has 3 correct and 1 wrong... manually I think it is not possible for me.

Excel Facts

Can a formula spear through sheets?
Use =SUM(January:December!E7) to sum E7 on all of the sheets from January through December
Hi,</SPAN></SPAN>

In other words in the example-3 I want those combinations in the columns J, K, L, M which can pass at least 3 correct out of 4 "with any of one results come out from 81 total combinations out of columns C, D, E, F" </SPAN></SPAN>

Note: As in example-2 if any of 27 combinations columns C, D, E is checked with betting columns H, I, J there are 2 correct always </SPAN></SPAN>

Thank you in advance</SPAN></SPAN>

Hi,</SPAN></SPAN>

May I have not explained it well in the #post1 some time it complicate to explain but may this can describe better my need hope so...
</SPAN></SPAN>

Example...result has come out X-1-1-2 if we check with 81 bets it has passed 4 with combi nº 30 shown highlighted in yellow cells H34:K34 so far betting 81 we sure that always at least 1 of the 4 will passed correct
</SPAN></SPAN>

As we already have the 81 bets of the of 4 triples (3*3*3*3=81) we are going to see what needs to be done to have a smaller combination but that always fails at most one sign, that is to say that it has at least one bet with 3 hits.
</SPAN></SPAN>

Now for example result is a same X-1-1-2 and if I would have bet only 2 out of 81...
</SPAN></SPAN>
1st...1-X-X-X in this one passed only 2
</SPAN></SPAN>
2nd...X-X-2-X in this one passed only 2
</SPAN></SPAN>

So far these are not valid because we need the combinations at least one bet with 3 hits.
</SPAN></SPAN>

Example for 81 bets could be...

I need to find the few smaller combination but that always fails at most one sign. In the any case any of the 1 result is out of the 81 bets.

From a mathematical point of view, this is really interesting. I'm sure someone has done some research on this. Mathematically it would be defined something like: "Given a set S containing sets of ordered elements, find a subset T of S containing a minimal number of sets of ordered elements such that every set in S differs by at most 1 element from a set in T." Something in graph theory maybe. Doing a quick web search didn't reveal anything, so I tried coming up with my own algorithm.

First up is a basic "greedy" method. Just go down the list of combinations, and every time you find one that doesn't match your rules in the subset, add it to the subset. It certainly works, but is not guaranteed to find a minimal subset. In your 3-team example, it came up with 8 teams, while you had 6.

Next I tried a brute force method. I figured with a small enough set, a fast computer could find an optimal set. It worked quite well for 1 team. For 2 teams it came up with the same sets you did. For 3 teams, I got this result:

You only need 5 sets instead of the 6 you have.

Looking good so far, but here's where the vast number of combinations kicks in. The macro ran for hours without finding a solution. I do know that it would require at least 8 sets to make it work. I'm trying to find a way to use various symmetries to reduce the number of calculations. I'll let you know if I figure it out.

Eric, your hunt for reducing down at least minimum to 2 must pass, within the 5 matches you discovery is accurate.</SPAN></SPAN>

Here are the results I did check are spot on!

With the 3 teams you got 5 results. Based on those results I made 3 columns to count the 1, X and 2 and then filter as per column K "filter criteria" and found the column as you discovered.

Here are the results...

Hi Eric, I were checking it would be 14 not 8 as shown below with 8 there are some with 2 pass the goal is find with minimum 3 within the 4 teams...</SPAN></SPAN>
