[Tex/LaTex] How to have continuation indent in algorithmicx algorithm for long comments and States

algorithmicx

Assuming that I can apply the same solution to my document, previously I asked how to have continuation indent in line comments on somebody else's MWE and got an answer.

However, I could not apply that solution to MY document. So I am re-posting a MWE with keeping my preamble, with following questions:

1-) How to have continuation indent in the line comment below?

2-) While you are at it, can you add continuation indent to the long \State, too?

Best Answer

The key problem was that there was a necessity to use comment as a parameter to \LineCommentCont, instead of \LineCommentRun Run the... which took only the first letter we must write \LineCommentRun{Run the...}. I created a new command named \MyState to handle multiline state situations. I enclose an example and a preview of the result.
