Re^4: Algorithm for cancelling common factors between two lists of multiplicandsby BrowserUk (Pope)

Sorry sk. I try to always attribute ideas, but it's been a long thread, several days and I've had other conversations beyond the thread. I may have misremembered the sequence of things.
For the algorithm, the problem is the implementation not the sort'n'subtract. With 4 values on top and 5 underneath, there are numerous ways in which the subtraction needs to be done. Ie.
And for low numbers, the time spent ordering and eliminating outweigths the benefits.
It's just a case of coding the mechanism in an economic fashion.
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
The "good enough" maybe good enough for the now, and perfection maybe unobtainable, but that should not preclude us from striving for perfection, when time, circumstance or desire allow.
