 English term or phrase: Order of a calculation I am editing a paper on the effects of an oil pipeline on permafrost, and the author would like to find a term to describe the process for reducing the number of calculations needed to solve a problem. She has made mention of the "Order of the problem" and the "dimension of the problem" but is not sure of the correct terminology, and neither am I. Any suggestions? Thanks in advance for your input!

order of a calculation
scale of the problem

Explanation:
That's one term we would often use for a physical 'problem' — "it was only once the flood-waters had subsided that they could see the true scale of the problem"

I'm rather less sure, however, if it will sit well when applied to a more abstract 'mathematical problem'? It probably could work alright, but it does rather depend on exactly how it is to be used in a sentence?

"In order to reduce the magnitude / scale of the task involved in analysing the dynamics of soil temperature, it makes sense to group together TCs at sites with similar physical/geographic and permafrost conditions."

 Asker: The sentence (as wtritten by a non-native speaker) is "To reduce the dimension of the analysis task of soil temperature dynamic, it is rational to group TCs located at sites with similar physical-geographic and permafrost conditions."

-> Thanks, Henk!

neutral  Daryo: or possibly "order of complexity"
 1 hr
-> As Terry says, any mention of 'order' is unsuitable here, because of its technical meaning; all this would do is make the sentence more clumsy and rather pompous in register.

I don't think there is a standard mathematical term for "reduce the number of calculations"; I don't see what is wrong with incorporating it in the sentence, e.g.

"To reduce the number of calculations in the analysis of the soil temperature dynamic, TCs at sites with similar physical/geographic and permafrost conditions are grouped together." (or "have been grouped together" depending on the tense being used).

 Asker: Could be. Personally, I would be satisfied with this, but she seems to be pressing me to come up with some standard mathematical term.

agree  Tony M: Another way of taking it... / And I don't believe there IS any 'standard mathematical term' — the original sentece simply refers to making the "task" les complex = simpler.

 This is what the author finally went with.

agree  Didier Fourcot: Technically much better than source, however is it an editor's job to heighten the language level?
 50 mins
-> good point, but as I understand it, the point of this question was to get the right technical term / to use the "trade jargon" / to indulge in the "expert's lingo" ... Thanks!

neutral  Tony M: I don't think this is a technical issue of 'computational complexity' (as one might find, e.g. at program code level) but simply of 'making the job easier'; note original author's use of 'task', which clearly points to the less formal sense here.
 1 hr
-> "computational complexity" has more to do with the complexity of the algorithm used, no matter if the calculation is done with pen and paper or using a supercomputer ...

disagree  acetran: . Welcome "New" Moaner-in Chief!

-> the notion of "complexity" too complex for you? a single dot is really an extremely convincing argument ... or it's some new minimalist fashion I'm not aware of, to be used as an excuse for laziness? or to hide the incapacity to string even a word?
