Always I have the message error about the float column width.
Undefined control sequence. \endalgorithm ...oatbox \global \setbox \@currbox \float@makebox \columnwidt... l.82 \end{algorithm} The control sequence at the end of the top line of your error message was never \def'ed. If you have misspelled it (e.g.,
\hobx'), type
I' and the correct spelling (e.g., `I\hbox'). Otherwise just continue, and I'll forget about whatever was undefined.
Anyone have some idea how can I fix this problem?
If you have some question let me know.
Thank you.
