how to remove spaces from algorithm and align nicely algorithm

Question

I want to remove the spaces between the "and" and the if clauses in the following code:

Please show us not only a piece of code, but a/some compilable minimal working example(s) reproducing your problems. — user156344

I mean that the code you show here is compilable, i.e. it has a document class, and begin with \begin{document} and end with \end{document} and also states the packages you used. Read more here. — user156344

i've removed the align tag, which is specific to the align environment in amsmath and replaced it by horizontal-alignment which covers the text situation described here. — barbara beeton

It's essentially impossible to typeset that piece of text in two-column mode, because of the very long identifiers.

I suggest to use algorithm* for typesetting it in single-column format and to use \raggedright.

Modifying the code to have algorithm instead of algorithm* you get overfull boxes because some of the identifiers simply cannot fit a line.
