(1/1)

I'll admit a lot of the stuff they were talking about was over my head, but
to me it appeared the second machine was treating this as a linear problem
instead of an exponential one.

Exponential (volume doubles each day):
Algae growth rate = StartQuantity * ( 2 ^ Days )
Days to fill reservoir = 30
Days to fill half reservoir = 29

Linear (volume increases by equal amount each day):
Algae growth rate = StartQuantity * Days
Days to fill reservoir = 30
Days to fill half reservoir = 15

Of course it still could have been a subtle math error and the fact
that it answered 15 was just a coincidence.

interesting to hear you perspective on this
...  it appears you where paying attention in math class and have reattained the numeric reflex's

of course  ;) *

... many potential methods to get to the correct answer , (presumably?) even more for less correct ones

which reminds me of count down

much ( :o if not all lol ) of the details are likely way over my head also

...however  wrt the (*wonders* of modern hardware  ) hw

Since AVX instructions are wider and generate more heat, some Intel processors have provisions to reduce the Turbo Boost frequency limit when such instructions are being executed.
