In the research group I am, we have usually try a few approach to each problem, let's say we get a:

Method A) 30% speed reduction and 80% precision decrease

Method B) 50% speed reduction and 5% precision increase

Method C) 740% speed reduction and 1% precision increase

and we only publish B. It's not brute force[1], but throw noodles at the wall, see what sticks, like the GP said. We don't throw spoons[1], but everything that looks like a noodle has a high chance of been thrown. It's a mix of experience[1] and not enough time to try everything.
