I have the following code for displaying an algorithm:

  \caption{Compute index of nearest grid point given particle position (1D)}
    \Function{FindMeshIndex}{$position$, $nGrid$}
      \State $index=math.floor(position+0.5)+((nGrid/2)+1)$
        \State $index=nGrid-1$
      \Return $index$

enter image description here

The output places the endif and return statements on the same line. Is there some formatting nuance that I have missed?

\Return doesn't issue a new line in the algorithm. You could force this through a redefinition:

enter image description here

  \caption{Compute index of nearest grid point given particle position (1D)}
    \Function{FindMeshIndex}{$\vars{position}, \vars{nGrid}$}
      \State $\vars{index} = \func{math.floor}(\vars{position} + 0.5) + ((\vars{nGrid}/2)+1)$
      \If{$\vars{index} = -1$}
        \State $\vars{index} = \vars{nGrid} - 1$
      \Return $\vars{index}$

\Return has been redefined to issue a \State first.

I've taken the liberty of defining \vars (for variables) and \func (for functions) which could improve your algorithm display.

    Or, if you only use it once you could simply write "\State\Return" instead of "\Return". – marczoid Oct 18 '17 at 19:19
\State \Return your-text

will fix it.

    I disagree with downvotes. The other answer fails to suggest this simple strategy. – egreg Jan 9 '18 at 7:17

    How does this differ from the previous answers? – TeXnician May 9 '18 at 12:01
  • The two previous answers say: 1. \let\oldReturn\Return; \renewcommand{\Return}{\State\oldReturn} 2. \State \Return your-text – Alexandre Huat May 14 '18 at 9:09

Another simple solution is to add \\ at the end of the previous State.

\State bla.. bla.. bla.. \\
\Return bla..
  • Welcome to TeX - LaTeX! This works here. It would be nice if you could make this into a complete small document and upload a picture of the output too. – Andrew Swann May 25 at 9:18
