Background: I have done a scientific project as a part of my graduation program and now iI want to present my work through presentation slides.
Query: There were some techniques which didn't work and imeant I had to anotheremploy other techniques. So, iI want to name those techniques on a single slide, but iI am unable to find a suitable title for that slide. I don'thinkdon't think that iI should use "Challenges" as the title, because iI think that itthat would only be suitable for those techniques which poseposed some problem to me but iI managed to solve them somehow.
So, whatWhat should be the title of mythe slide on which i want to writeI present the techniques that failed?
