    First of all, is this a world thatt you have played?

    Your replies were excellent. Thank you for participating.

    You should also account for players who use text seeds, though since there are only about 4.3 billion possible seeds it doesn't change much (while Java's Random can generate 65536 times more unique seeds there is almost no overlap between the seed spaces - in fact, just 65536 text seeds can be expected to match a randomly generated seed since Random can only generate 1/65536 of all possible seeds).

    Also, while I have created many worlds, possibly more than a thousand, I often reuse the same seed;



    I would like to tell you that i am talking only about randomly generated seeds, not text seeds. With that i mean blank seed box (or 0).

    Also i took account in the calculation that some players create worlds, but with the same seed and adjusted it.

    Quote from BigAlanM»

    If you want a world that is extremely UNLIKELY to have been seen by another player there is an easy way to get one (actually a HUGH number of them).


    Now, since the pseudo random number generator is ASSUMED to give each number in that range an equal chance of being generated there is something we can say with certainty. The chances of a generated number having LESS than 16 digits is nearly 10,000 to 1 AGAINST.


    Each decrease in seed length increases that probability by a factor of 10.
    So the probability of the PRNG of generating a 13 digit seed is 10 MILLION to 1 AGAINST. ie not very likely.


    So, If you want to create a world that, in all probability, has NEVER been seen by another Minecraft player, just use any positive or negative number with 11 through 15 digits. I'll bet anything your world will be unique.


    Good calculation! Just a reminder that we are talking about random seeds, not inputed/text.


    Also i would like to include that, if one 4221th of all seeds are generated (based of my calculations), then the most "rarest" seeds by digits are 6 ten or less digit seeds. A 10 digit seed looks like this: 1.000.000.000

    This also means that these seeds can be generated by text.

    So it means that, only 6 worlds have been randomly generated that can be generated by text.

    Also there is a 60% chance of a 9 digit seed (it looks like: 10.000.000)

    And a 6% chance of an 8 digit seed (it looks like 1.000.000)

    posted a message on Have all possible random seeds been already generated?

    So my question is in the title. Have all possible random seeds been generated?

    If you don't know, minecraft has 2 to the power of 64 possible seeds, which is this number:

    18.446.744.073.709.551.616‬

    HOWEVER: Only 2 to the power of 48 seeds can be generated [b]randomly[/b] because of a problem in java random, which makes the possible seeds:

    281.474.976.710.656‬

    This is 281 trillion. That are lots of worlds.


    Another way to ask this question is: "If i generate a world, has my world been generated by another user?"

    OR "Have ever 2 players got the same world?"


    Now, lets go for calculation. It is difficult to calculate how many worlds all users have generated. Some have generated 1, others (speedrunners) 10.000.

    It is very difficult to calculate, but i will make my best. On all platforms, minecraft has been sold 200 million times. If we include minecraft china, which has 300 million downloads (1/5 of china's population!), 500 million players have played it. (1/14 of the world!).

    Now the difficult part. Calculating.

    I started by calculating how many worlds i have generated and that is around 300.

    Now i need to check the average playertime. A youtuber called antvenom covered it and his video helped me a lot.

    So, 1/3 of minecraft players are alt accounts that possibly have not generated worlds or just 1. This means that 166 million accounts have generated 0-5 worlds. Lets put 0.5 worlds, so from these alt accounts, 83 million worlds have been generated, and that is still one 3.391.264th from all possible worlds.


    Now lets progress into the 2/3 of the accounts that are actual, i mean for the 333 million other accounts.

    Now it is very difficult. We have a range of 5 to 10.000 worlds, with some users even generating 100.000 worlds (i don't know how, but possibly a shared account with family and friends that are all creating worlds to check customized mode? i have no idea).

    I will make a wild guess and claim 200. This means that the average player has generated 200 worlds. And that is 66 billion worlds. Still one 4.226th of all possible random world seeds.

    Adding the 2 values together, and we get 66.683.000.000 worlds FROM ALL USERS OF MINECRAFT. one 4.221th of all minecraft seeds.

    The number above (66 billion worlds) may seem a bit small, but remember, it is like each human on this planet to have generated 8 worlds if we put it on that scale.


    So my final answer is that only one 4.221th of all seeds have been generated. This means that if you generate 4221 worlds, you have a very high chance that another player has generated the same world. Or if you generate a world, you have a one in 4221 chance that another player has generated the same world as you. Or, there is a one in 4221 chance that a player has generated the seed 0. Or a one in 4221 chance that somebody generated the seed for pack.png (except mojang).


    I did my best, but if you have another possible answer that increases the amount, please let me know.


    EDIT:

    Also i would like to include that, if one 4221th of all seeds are generated (based of my calculations), then the most "rarest" seeds by digits are 6 ten or less digit seeds. A 10 digit seed looks like this: 1.000.000.000

    This also means that these seeds can be generated by text.

    So it means that, only 6 worlds have been randomly [/b]generated that can be generated by text.

    Also there is a 60% chance of a 9 digit seed (it looks like: 10.000.000)

    And a 6% chance of an 8 digit seed (it looks like 1.000.000)

    posted a message on How tall is the tallest naturally generated cactus?

    So, if i read correctly, the highest possible cactus is 90 blocks, and the chance is 1 in 1000000000000000000000‬, making it impossible for maybe every seed because of the RNG.


    Do you know if there is any program that finds the tallest cactus from all minecraft seeds and all locations?

    Maybe this thread will become the "tallest cactus hunt".

    posted a message on How tall is the tallest naturally generated cactus?

    The title says it all.

    I don't mean the tallest that can be built but the tallest that is naturally generated.

    I mean the tallest cactus from ALL seeds in minecraft.

    If i am talking correctly, somebody in minecraft wiki bruteforced a 12 block tall cactus at 0,0


    My idea is:

    If we can brute force a very tall cactus at (almost?) any location, then what it the tallest possible cactus, after searching ALL seeds and ALL locations?


    Feel free to ask questions and if you have an answer pelase reply.

    There are no screenshots found. Can we use this rare combination of structures less than 150 blocks from spawn to find anything?
