"Maxima" is plural, "maximum" is singular. So you would say "a local maximum," or "several local maxima." Not "a local maxima" or, the one that really got me, "getting trapped in local maxima's."
As for the rest of it, carry on. Good discussion.
- FeepingCreature 3y agoA local maxima, that is, /usr/bin/wxmaxima...
- erisinger 3y agoTouché...
- gyrovagueGeist 3y agoWhile "local maximas" is wrong, I think "a local maxima" is a valid way to say "a member of the set of local maxima" regardless of the number of elements in the set. It could even be a singleton.
- Tijdreiziger 3y agoYou can't have one maxima in the same way you can't have one pencils. That's just how English works.
- pixl97 3y agoYou can't have one local maxima, it would be the global maxima. So by saying local maxima you're assuming the local is just a piece of a larger whole, even if that global state is otherwise undefined.
- reverius42 3y agoNo, you can’t have one local maxima, or one global maxima, because it’s plural. You can have one local or global maximum, or two (or more) local or global maxima.

- dragonwriter 3y agoNo, a member of the set of local maxima is a a local maximum, just like a member of the set of people is a person, because it is a definite singular. The plural is also used for indefinite number, so “the set of local maxima” remains correct even if the set has cardinality 1, but a member of the set has definite singular number irrespective of the cardinality of the set.
