algorithm2eifthenelse
I have the following example
\documentclass{report}
\usepackage{algorithm2e}
\begin{document}
\begin{algorithm}
\lIf{$\max_{\mathcal{AV}} > \theta_5$}
{
\Return the tracklet with $\max_{\mathcal{AV}}$.
}
\lElse
{
\Return no speaker.
}
\end{algorithm}
\end{document}
however I do not want if and else be in two separate lines, but only in one.
Could anyone help me, please?
Thanks in advance
Supposing your document is in German , loading babel with german set via document class does the trick. To replace end with endfor, overwrite the definition of For with \SetKwFor:
\documentclass[german] {article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{babel} \usepackage[linesnumbered, ruled, vlined]{algorithm2e}
\SetKwFor{For}{for}{do}{endfor for}%
\begin{document}
\SetAlgoNoLine
\begin{algorithm}[H]
\DontPrintSemicolon
\KwIn{$X_{t-1}, u_t ยท z_t$}
\KwOut{$X_t$}
$\overline{X_t} = X_t = 0$\;
\For{$k = 1$ to $M$}{
$x^{[k]}_t = sample\_motion\_model(u_t, x^{[k]}_{t-1})$\;
$w^{[k]}_t = measurement\_model(z_t, x^{[k]}_t, m_{t-1})$\;
$m^{[k]}_t = updated\_occupancy\_grid(z_t, x^{[k]}_t, m^{[k]}_{t-1})$\;
$\overline{X_t} = \overline{X_t} + \langle x_x^{[m]}, w_t^{[m]} \rangle $\;
}
\For {$k = 1$ to $M$}{
draw $ i $ with probability $\approx w_t^{[i]}$\;
add $\langle x_x^{[m]}, w_t^{[m]} \rangle$ to $X_t$\;
}
\Return $X_t$

\end{algorithm}

I missed the part in the algorithm2e manual when it is stated that the option H makes the environment non-floatable, thus it could be put inside the tcolorbox environment.
This is the updated code:
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[longend]{algorithm2e}
\usepackage{textgreek}
\usepackage{amssymb}
\usepackage{tcolorbox}
\begin{document}
\begin{tcolorbox}[fonttitle=\bfseries, title=Q-learning (off-policy TD control) for estimating $\pi \approx \pi_*$]
\begin{algorithm}[H]
Algorithm parameters: step size $\alpha \in (0, 1]$, small $epsilon > 0$\;
Initialize $Q(s, a)$, for all $s \in \mathcal{S}^+, a \in \mathcal{A}(s)$, arbitrarily except that $Q(\mathrm{terminal}, \cdot) = 0$\;
\ForEach{episode}{
Initialize S\;
\ForEach{step of episode}{
Choose $A$ from $S$ using policy derived from $Q$ (e.g., \textepsilon-greedy)\;
Take action $A$, observe $R$, $S'$\;
$Q(S, A) \leftarrow Q(S, A) + \alpha [R + \gamma \max_a Q(S', a) - Q(S, A)]$\;
$S \leftarrow S'$\;
}
}
\end{algorithm}
\end{tcolorbox}
\end{document}
This is the visual result:
Usually, I don't post self-answered questions. This was a genuine question but I found the answer five minutes after I posted it. Since it could be helpful to others I will leave it here.

Define
\lIfElse{<condition>}{<true>}{<false>}to insert the<false>clause as part of<true>:
