Can a scientific article (of an non-tested idea) in computer science be accepted in a high-ranked journal? I'm doing a PhD in computer science. I've been working in my research question for a year and a half now and I still didn't publish any article yet. Lately, I found out an idea that can improve the current solutions. I believe my idea can provide better results than current tools. But, my question is as follows: Is it possible to submit my paper to a scientific journal and hopefully get it accepted without implementing my idea (i.e. without testing my idea)?
Ideas are cheap. Most researchers have more ideas than they have time to develop them. It's the development which has value. Or to put it another way, in order to advance the field you need to convince other people that your idea is interesting, and the fact that you believe it will not be sufficient. Depending on your subfield the way to convince people may be a mathematical analysis, empirical measurement of an implementation, or a combination of the two, but you need something.
