### Re: problem 155

Claude,

to answer your first question:

D(13) is indeed a 5-digit figure but it starts with 3 and ends with an odd digit.

### Re: Problem 084

Well, I sit here and are completely baffled. Got desperate and tried my code with two 4-sided die, and guess what; Green Tick :shock: [edit] an admin may edit this if it reveals too much: had to revert to numpy for random dice throws as the standard random implementation in python is too unreliable ...

### Re: Problem 084

Yay! my code keeps insisting that "100024" is the modal string for two six-sided die :-D That's a tad bit frustrating .. Ah, and I implemented the rule to just accumulate the doubles except there are 3 of them, otherwise my result would be "101918" :shock: [edith says:] now that I ran it for a coupl...

### Re: Problem 622

Really interesting little problem (imho 15% is a bit low) In the mean time I know exactly what the maximum deck size for s(n) = 60 is, or any other amount of shuffles for that matter, (No, you can't shuffle this deck by hand or even forklift :D ) but the decks in between are still a mistery to me. Y...

Finally!

one minor tweak made it general use ... Phew, that was hard work. [you may visit the problems forum post #91 to make fun of me ]

Now only one to go to reach level 8

### Re: Problem 485

Crickey!

this was a real brainf* regarding zero based indexes and bounds and predictive computing in reachable ranges.

Brain hurts big time, but now I got the test case correct (below 1 msec)

[edit] sure enough my final answer is still wrong! I hate this problem [/edit]

### Re: Problem 485

Hi Ken, good hint, but my Divisor Count function is ok (got the correct result for S(1000,10) by doing it the naive way, which would take days for the original Problem) There is something obvious wrong with my S() implementation which I just don't see yet .. proofed only test cases yet, maybe there ...

### Re: Problem 485

I keep getting 16739 for S(1000,10), pretty fast but obviously wrong. This drives me mad :evil: I'm pretty sure my algo for S() should work though. Got the wrong result for the problems answer in about 126 seconds :mrgreen: Anyone keen to give a second pair of eyes on my python code, or experienced ...

### Re: Problem 420

Nope, sorry. Still don't get it. Seems that I'm a bit thick today :( [edit] The only thing I see there is that the ratios on the diagonals are the same in every matrix, but how that accounts for those lesser matrices to be squared? No clue[/edit] [edit 2] Animus was so kind to link me to the corresp...

### Re: Problem 420

I don't get this at all.. Can someone explain to me how these matrices relate to each other? The sum of those matrices are different and I just can't make out any other relation :oops: taking the sample: https://projecteuler.net/project/images/p420_matrix.gif Maybe I'm just a bit undercaffeinated?

well, yeah, sure. Thanks

Can someone confirm the 1000th number with at least 5 Prime Factors to be 9576 ?

### Re: Problem 333

... way too long to get even sum P(q)=1 for q<10**3.

4600 in a bit more than an hour m(

Can't think of any other good way to optimize that anymore, there are way too many partitions to check.

There has to be a simple rule/formula for excluding terms in this, but damn, do I suck at maths

I kind of left them out by purpose.. thought once again incorrectly that a partition must consist of n>1 elements. m(

Now to make this bugger efficient. Runs way too long to get P(q)=1 for q<10**6

### Re: Problem 333

Resuming the problems after a long break. My terms for q <100 are [2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 64, 72, 81, 96] my result for P(q)=1 for q<100 is 228 (instead of 233) :shock: Has anybody any clue where I'm going wrong? My primes with P(q) = 1 are 5 7 13 17 23 43 59 61
