I started working on my PhD few months ago and I am trying to solve a problem in a particular topic. The topic is quite specific and many people have already worked on it before. I am stuck at the following two scenarios:
I would like to extend the topic in some particular direction which I think is interesting and new. How will I know if people have already worked on that 'new extended topic'? I google hoping to find something, but I don't. I read some review papers (but most of them are old) and they don't cover any. Also, I think it is very difficult to read all recent papers related to the topic of research in a hope to land on my specific topic.
I would like to solve an existing specific topic in a new way, which may be quite simple, but looks efficient. But, I have the feeling that people should have already solved the problem in 'my new way'. How will I find if that has been done? I use google again and land up in quite interesting papers but it still do not solve my problem.
How do you guys tackle the above situations? I think one way is to do a very extensive literature review of the topic, but how will you achieve that? Review papers? Reading 'all' papers in that topic? I tried to do that right at the beginning, but I realized I can not and should not know everything, but should have a very rough overview of the topic and in depth knowledge in my way of solving the problem.
