Has anybody used the KIFMM (https://web.stanford.edu/~lexing/fmm.pdf) for the Yukawa potential?

2$\begingroup$ please clarify your question and perhaps elaborate on what you mean by "special scaling" $\endgroup$ – sssssssssssss Sep 26 '18 at 11:20

$\begingroup$ If I could I would, but I do not know which scaling that is needed. It just says so on their webpage. Concerning the KIFMM I wonder if anyone has applied it successfully on the Yukawa potential. $\endgroup$ – Raibyo Sep 27 '18 at 12:25

2$\begingroup$ Then, how do you expect to obtain suggestions? $\endgroup$ – nicoguaro♦ Sep 27 '18 at 13:58

2$\begingroup$ The KIFMM is kernel-independent, meaning (in this instance) that you can feed the FMM algorithm a handle to your kernel function and it evaluates the N-body type calculation in O(N) time. The Yukawa kernel is no exception. It seems likely to me that the "scaling" you're talking about refers to a particular optimization of the FMM implementation when the kernel function is homogeneous, i.e. $K(ax,ay)=a\cdot K(x,y)$. $\endgroup$ – smh Sep 27 '18 at 20:21

1$\begingroup$ You edited the question, but still it is not the best fit for this site. Let's suppose somebody "answer" it saying: "Yes, I have." Try to explain what have you tried, the context for your problem and where are you having problems. $\endgroup$ – nicoguaro♦ Oct 2 '18 at 2:42
