What is wrong here? In this paper, we discuss the problem of
computer visions.

Count vs non-count We study computer vision. (non-count)
Joan of Arc had visions. (count) She saw God and He told her to go to war.
He saw a vision in a red dress. (count) A vision = an amazing-looking woman

In an abstract Our method solves the 18 queens
problem in 6.96E+3 milliseconds

6.96E+3 milliseconds Just say 6960 milliseconds
Better: 6.96 seconds
In an abstract, maybe just: Under 7 seconds

Reviewing your own paper Spelling checker & grammar checker
Can you simplify? Nouns to verbs? Move data to tables?
Can anything be cut? Is there repetition? On my own papers, I shorten about 30%.
