Recaman S Sequence Rosetta Code The recamán's sequence generates natural numbers. starting from a (0)=0, the n'th term a (n), where n>0, is the previous term minus n i.e a (n) = a (n 1) n but only. The recamán's sequence generates natural numbers. starting from zero, the n'th term a(n) is the previous term minus n i.e a(n) = a(n 1) n but only if this is '''both''' positive ''and'' has not been previousely generated.
Recaman S Sequence Rosetta Code In mathematics and computer science, recamán's sequence[1][2] is a well known sequence defined by a recurrence relation. because its elements are related to the previous elements in a straightforward way, they are often defined using recursion. The idea is to generate the first n terms of recaman’s sequence by following its recurrence rule. we start with 0 and iteratively compute the next term as previous term index if it is positive and not already in sequence; otherwise, we use previous term index. Recamán's sequence (or recaman's sequence): a (0) = 0; for n > 0, a (n) = a (n 1) n if nonnegative and not already in the sequence, otherwise a (n) = a (n 1) n. The rules for the visualization are that you connect consecutive elements of the sequence with circular arcs, alternating arcs above and below the number line. here’s code to reproduce an image from the video.

This sequence starts at 0 and the nth number in the sequence is the result of moving forward or backward n steps from the previous number. you are allowed to move backward if the result is positive and a number you haven’t already visited. Using a numerical approach, i generated sequences for various functions and visualized them using both traditional plots and jump plots (where semicircles connect consecutive values). below you see well known plots of standard recamán sequence ($f (n) = n$):. There are at least two sequences attributed to b. recamán. one is the sequence formed by taking and letting. which can be succinctly defined as "subtract if you can, otherwise add." the first few terms are 1, 3, 6, 2, 7, 13, 20, 12, 21, 11, (oeis a005132), illustrated above. a view of the first 256 terms as binary bits is shown above. An interesting visualization of this sequence can be done with half circle representing the jump from a (n) to a (n 1). the idea of plotting the recaman sequence like this come from the channel numberphile in a video featuring alex bellos and edmund harriss.
