I have a std::list of Bananas, and I want to get rid of the bad ones.

I am trying to optimize further the champion solution in prime number thread by taking out the complex formula for sub-list length. len() of the same subsequence is too slow as len is expensive and generating the subsequence is expensive. This looks to slightly speed up the function but I could not yet take away the division, though I do...
In C# I wish to serialise a data structure where objects can belong to more than one collection. For example, I have a Person class. I also have a Family class and School class, which each contain a MemberList. An instance of the Person class can be present in both the MemberList of the Family and the School. I wish to serialise the en...

Given a list of elements, does a shuffling algorithm exist that will guarantee that eventually a selected half portion will be on one side, and the remainder on the other? Example: { 4, 3, 10, 7, 2, 9, 6, 8, 1, 5 } Given the set above, I'd like to have a mixing algorithm that eventually moves the marked ones to the left, even though...

My issue is that it could be anywhere from 1 to 1...
Suppose I have a list of things (numbers, to keep things simple here) and I have a function I want to use to sort them by, using SortBy. For example, the following sorts a list of numbers by last digit: SortBy[{301, 201}, Mod[#,10]&] And notice how two of (ie, all of) those numbers have the same last digit. So it doesn't matter which ...
For or While loops in Mathematica code always make me feel a little dirty but I was confusing myself trying to do some list munging all functional-like, and resorted to this: (* # Given a list of {x,y} pairs, transform the data as follows: every time # there's a decrease in y-value from one datapoint to the next, say {x1,Y} # fo...
