How many terms are in the longest Collatz sequence?
It can be seen that this sequence (starting at 13 and finishing at 1) contains 10 terms. Although it has not been proved yet (Collatz Problem), it is thought that all starting numbers finish at 1.
How to calculate the longest Collatz chain in Python?
The Python program listed in the Afterthoughts section shows the hailstone calculator for determining values in the Collatz chain for a number, N. The d function determines the length of the chain and the purpose of the program is to determine the longest length for a set of consecutive numbers below some limit, L.
How to find the longest Collatz in Euler 14?
Project Euler 14: Find the starting number, under one million, that produces the longest Collatz sequence. Project Euler 14: The following iterative sequence is defined for the set of positive integers:
Which is the longest sequence of consecutive numbers?
TL;DR: between 1 and n, the longest sequence of consecutive numbers with identical Collatz lengths is on the order of log ( n) loglog ( n) numbers long. I wrote a java program which finds long consecutive sequences, here’s the longest I’ve found so far.
Which is starting number under one million produces the longest chain?
It can be seen that this sequence (starting at 13 and finishing at 1) contains 10 terms. Although it has not been proved yet (Collatz Problem), it is thought that all starting numbers finish at 1. Which starting number, under one million, produces the longest chain?
Which is the longest Collatz sequence in Euler 14?
Project Euler is asking a question regarding the Collatz Conjecture in Problem 14 The following iterative sequence is defined for the set of positive integers: Using the rule above and starting with 13, we generate the following sequence: It can be seen that this sequence (starting at 13 and finishing at 1) contains 10 terms.
