During an exploration of mine in Wikipedia i saw this cool article talking abut Problem Solving.Then i scrolled down in this article until i saw "Common barriers to problem solving". It said:
Common barriers to problem solving are mental constructs that impede our ability to correctly solve problems. These barriers prevent people from solving problems in the most efficient manner possible. Five of the most common processes and factors that researchers have identified as barriers to problem solving are confirmation bias, mental set, functional fixedness, unnecessary constraints, and irrelevant information.
Now when i saw the explanation of those terms,it seemed to me like it made perfect sense.At least in my case when i try to solve \(150+\) points valued problem these are the exact barriers that dont let me solve the problem(most of the time the first three ones).Can someone tell what book should i read such that it will help pass these barriers because that is exactly what i need to step onto the next level in math and to able to compete with geniuses like Daniel Liu, Krishna Ar , Sean Ty,Pi Han Goh and so many others here.Please!!!Help!
