How to fix space before and after algorithm

algorithmsfloats

I am working on IEEE 2 column format and I wrote algorithm but the algorithm is not able to fix in the column as it has free space above and below the algorithm as shown in figure how to solve this issue

     Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, radiation, and physical
      properties of matter. The behavior of these quantities is governed by

      description using measurable macroscopic physical quantities, but may
      be explained in terms of microscopic constituents by statistical
      mechanics. Thermodynamics applies to a wide variety of topics in

The issue here is that the algorithm doesn't fit within the current column and is therefore pushed to the next one and since there's no text to float around, it centers the float within that column. Add more text and the float display should allow for the "proper" spacing/layout.

[Tex/LaTex] How to remove/change the vertical spacing before and after an ‘algorithm’ environment

LaTeX has three length variables to control (i) the distance between two adjacent floating objects (such as figure, table, or algorithm objects), (ii) the distance between a float at the top (bottom) of a page and the text below (above) it, and (iii) the distance between an in-text float and the text above and below it; they are called \floatsep, \textfloatsep, and \intextsep, respectively. (LaTeX also has three more such variables to control the spacing above and/or below floats on floats-only pages; these are \@fptop, \@fpbot, and \@fpsep, respectively.)

To completely suppress the in-text separation of a float (not recommended, by the way!!), you'd type (in the preamble)

\setlength{\intextsep}{0pt}

i.e., you'd set \intextsep to a fixed length of 0 points. A better solution, if you're pressed for space (pun intended), would be to set

\setlength{\intextsep}{1\baselineskip}

Here's a MWE that uses the algorithm2e package:

\documentclass{article}
\usepackage{algorithm2e}
\newcommand{\lipsone}{Lorem ipsum dolor sit amet, consectetuer 
adipiscing elit. Ut purus elit, vestibulum ut, placerat ac, 
adipiscing vitae, felis.}
\newcommand{\lipstwo}{Donec vehicula augue eu neque. Pellentesque 
habitant morbi tristique senectus et netus et malesuada fames ac 
turpis egestas.}

\KwData{Some input}[h]
\KwResult{Some output}

\end{algorithm}

\lipstwo


\subsubsection*{After setting \texttt{\textbackslash intextsep} to 0pt}
\setlength{\intextsep}{0pt} 
\lipsone

\begin{algorithm}
\caption{Another random example}

[Tex/LaTex] Algorithm tag and page break

Here are some suggestions:

If you're adding your algorithm inside the algorithm float, then it will float according to the "float specifiers" given as the optional argument to the algorithm environment. For example
```
\begin{algorithm}[ht]
  ...
\end{algorithm}
```

To force the float to be less float-y, add ! to the float specifier. However, as suggested by the float package, this still remains a "suggestive specifier". Instead, the package provides the additional H float specifier which tells LaTeX to "PUT IT HERE!"

Use the algorithmx package. It is very similar to algorithmic, but allows for more flexibility. Here's a short, yet complete, minimal example (from the algorithmicx package documentation).
If you wish to have the algorithm break across the page boundary, you have to set things up differently. I've incorporated a breakablealgorithm environment below.

The above redefinition of \caption assumes that it will be placed where it's located in the algorithm; specifically at the top. Rule definitions were taken from the float package's \@fs@ruled construction.
