I have written a small paper that I have written in the field of computer science. I've had several people read it, and one recommended that it's of enough quality they think I should be able to publish it in a journal. I'd like to explore this option, but almost every reputable journal I can find requires a large sum of money to publish in their journal, which is not an option for me, as I am not affiliated with any institution and cannot spend that amount of money.
Are there any journals in computer science that don't require a large amount of money to publish with? Or will I simply have to do something along the lines of publishing on something akin to arXiv and not continuing past there?
