I am working on a research project whose eventual conclusion is probably several years away. However, I have some intermediate results that are:
a) Useful for practitioners in the field b) Useful as stepping stones towards the eventual complete solution
I'm thinking of writing up these results in a paper with the title: "Towards a closed-form solution of grasp statics". My question is, is it correct to use "towards" here to indicate that the paper is presenting a piece of an as-yet incomplete solution?
Using "towards" in a title is perfectly acceptable, as indicated by the large number of papers that you can find with this word in their title.
I've also used it myself, in just the sort of manner that you are considering, and found no objection from reviewers.
