Huge computation cost or large computation cost? which one should I use?

Question

I see this huge or large. Which one should I use?

I got

However, something huge is surprisingly large or excessively large. If something is large, but about as large as can be expected, then it is not huge.

I have some doubt as

Due to huge computation cost, this method is not widely used.

Due to large computation cost, this method is not widely used.

Need some suggestion.

Answer 1

Both huge and large would be acceptable in this situation. Huge would emphasise the size of the cost more, but large would more likely be used in formal contexts.

To describe the cost, you should be using the adjectival form of computation - computational. Given that you are referring to one unique thing (the cost), you should be using the definite article as well. Your sentences would then become:

Due to the huge computational cost, this method is not widely used.

Due to the large computational cost, this method is not widely used.

Answer 2

I wouldn't use large. 'High' sounds much better. 'Large' suggests spatial dimension, while 'high' is more about the number you are obtaining in the benchmark. 'Huge' is non-technical and too informal. As a computer scientist, I wouldn't be persuaded by your comment unless you give some complexity measure or cost analysis.
