    All programs from JLP are perfectly optimized and if it were possible to improve the result, then the author would definitely do it.

    To "double the speed" there is only one solution.
    This is to use not only the addition of the kangaroo jump, but also the subtraction.
    This will not require many resources, but will double the number of tested points and thus the number of  distinguished points.
    But it will also slow down the progress of all kangaroos.
    Can this help, maybe, or maybe it will just overload the hash table with extra distinguished points.
    With this modification also need to turn off the check for dead kangaroos, because a kangaroo hitting the same position that was left
    after the subtraction does not mean that the kangaroo is following the trail of another kangaroo.
    But as i said above, the author would have done it if it had worked.
    Etar, you are a smart programmer. It’s really not that much to mod. I made some simple mods and increased speeds by at least 3x on most cards.

    But hey, y’all can say what you want to. Water off my back.

    Maybe I’ll make a video to compare how many DPs JLP’s stock Kangaroo can get in x amount of minutes and then compare that to mine. But even then, there would be doubters.

    But we can do a test; a timed test. Someone can give me a range, say a 44 bit range and I will run it with my mod at DP 29, and post results. 44 bit range with DP 29 should yield 2^15 DPs in 38 minutes using 1 RTX 4090.

    That is not true, the programs that he did, can be improved a lot.
    Some optimizations that give a few percent or even 10-20 maybe someone can improve.
    But an optimization that gives an increase of 2 times is unlikely.
    I will bet you whatever you have to lose 😎

    For example my BSGS version is almost times 3 times 9 times faster that the Original BSGS from JLP, that is almost 300% 900%

    just saying...

    edit

    click for proof 🖼️

    With the same RAM JLP did that range in 3 hours, i did it in 20 minutes that is 900% faster...

    Substaction jmp distance from kangaroo position will give a doubling in the speed of finding  DP.
    But will these additional points give a result?
    If you found another solution, then well done. I only found this way.

    I believe @ _Counselor implemented this method; he would know if it gave any significant speed up. But if I remember, I believe he said it did not.

    Im agree with you! I just wanna know how much speed kangaroo have with 4090 in Stock WO powerlimit..May be I doing something wrong but my speed on 4090 nearly Tesla V100 32Gb  1420 MKey/sec speeds



    Out the box, non modded Kangaroo with 128x128 grid size. Should be in the 2200-2300 range.

    How to get all addresses + privateKey starting with 16jY7qLJn from #64?
    More interesting all those on this same range of 64 starting with 16jY7qLJnx?

    You would have to run the entire range, in the range you are wanting to search.

    No, I do not think so because it covers the whole range #64 with this prefix 16jY7qLJnx
    So 18 obtained on a purely theoretical and probabilistic distribution of 21 on this range with this prefix 16jY7qLJnx

    Yeah, not sure what you really mean then. How can you be certain a 16jY7qLJnx prefix isn't in a range without checking every key?

    You said all addresses starting with 16jY7qLJnx, so maybe I am misunderstanding your question. Are you wanting 100% certainty or more like 30% lol.

    it remains only theoretical and probabilistic the distribution is obviously not linear if not on range #64 by adding an additional character to 16jY7qLJnx ex H ==> 16jY7qLJnxH it should come out <1 but in this case there are 2 whereas for 16jY7qLJnx N or P only one address but it stands

    I still do not understand what you are asking/implying.

    In the 64-bit range, there should be an estimated 2,483 addresses that start with 16jY7qLJnx.

    You are looking at a very small sample size in the list of addresses you posted.

    I think he want to work on the law of averages. So work on either side of long gaps so to speak. I could be off base though.

    It's strange did you notice that on #66 there is an output awaiting validation  2.07$  Huh
    https://www.blockchain.com/fr/explorer/addresses/btc/13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so
    It is not validated so the pubkey is not broadcast but the scale takes it into account without any validation   Total Received 6.60036526 BTC   Final Bitcoin Balance 6.60028826
    It doesn't exist on the other # yet. How can this happen?

    It's strange did you notice that on #66 there is an output awaiting validation  2.07$  Huh
    https://www.blockchain.com/fr/explorer/addresses/btc/13zb1hQbWVsc2S7ZTZnP2G4undNNpdh5so
    It is not validated so the pubkey is not broadcast but the scale takes it into account without any validation   Total Received 6.60036526 BTC   Final Bitcoin Balance 6.60028826
    It doesn't exist on the other # yet. How can this happen?


    It is not an output, is in input to the puzzle 66, nothing strange there.

    ok albert0bsd but my remark came from the fact that the explorer shows $2.07 sent as well as the difference between the total received and the final balance...so why  Huh

    It looks like pending inputs from my side. Not sure anyone can confirm. They not outputs, just unconfirmed in. Available but not.
    Look over there...
