comment Recurrence relation for a function with an integral of the function?
this looks like the right direction I think the miraculous cancellations are a feature, not a bug haha

comment Recurrence relation for a function with an integral of the function?
well, the more I looked at the "simplified" example I gave the more I realized that it just wouldn't do. The itnegral from 0 to 0 would be 0 and then g(1) would = 0 instead of the given starting condition of 1. The answer is most definitely not constant. I suspect it is a differential equation of the form above.

where a, b and c are all functions of f

comment Recurrence relation for a function with an integral of the function?
A friend suggested that the correct approach is differentiating the function thrice. However, I gave that an elementary stab using the Leibniz rule definitions I found online and I couldn't get rid of the integral itself. The solution should most likely be a differential equation in the form g'''(f) = a*g''(f) + b*g'(f) + c*g(f), which I should hopefully then be able to solve into g(f)

the fact that there is an initial condition suggested this is the approach, but I just cannot make it work

comment Continuous distributions on a vanishing length with an off-limits region
I apologize for any confusion in my terminology. I did mean uniformly, and the fraction is always on the right hand end. You have the same process as I, but my expected remaining lengths take it as a given that the slice actually happened, which why the probability that a slice what taken off in the previous round is actually 100%. So <pre>1-1/2*3/4=0.625</pre>
