How to use latex commands to draw a flowchart

Question

I have to write a flow chart given by figure below

enter image description here

I have used the packages,

\usepackage{tikz}
\usetikzlibrary{shapes,arrows}

But I couldn't get what I want. I hope some LaTeX experts here can help me with this.

Other option is using algorithm2e package, Is that possible to have both codes?

When I use the half commands it goes to other page? How to I write complete flow chart in one page ?

@PaulGessler the one I wrote terrible, code doesn't compile either — Harry, Mar 29 '14 at 00:05
possible starting point: Arrows at right angles on a tikzpicture matrix — cmhughes, Mar 29 '14 at 00:42
@cmhughes I just cut and paste and then run the given example above. But it doesn't compile — Harry, Mar 29 '14 at 01:27
@Harry did you run Jake's code? If it didn't compile for you, you might need to update your distribution: How do I update my TeX distribution? — cmhughes, Mar 29 '14 at 01:31
@cmhughes Yeah.I did that, but still I can't compile Jake's code. — Harry, Mar 29 '14 at 01:47
@cmhughes When I run the command both in WinEdt8 and tex studio, it stops at \path [>=latex,->] (m-1-1) edge (m-2-1); and every other \path commands — Harry, Mar 29 '14 at 02:00
Note that even code which doesn't compile or is 'terrible' will save people time in trying to help if only because you provide at least a minimal framework for the document. — cfr, Mar 29 '14 at 03:30
@cmhughes Does it compile for you? I get an error at the same point. I'm wondering if the problem is that my installation is updated so that I have tikz 3. I notice that code is from a bit ago and still, for example, uses arrows etc. — cfr, Mar 29 '14 at 03:34
It works if you label the nodes by hand or if you use a regular, plain matrix without specifying e.g. \node. — cfr, Mar 29 '14 at 03:48
May be you can look a this example http://texample.net/tikz/examples/flexible-flow-chart/ — Ignasi, Mar 29 '14 at 06:44
@cmhughes I have tried but it gives error. Could you please help me to finish this. Many thanks — Harry, Mar 31 '14 at 02:26
@cfr I have tried the code. Please refer to the modefied version of the problem. — Harry, Mar 31 '14 at 02:27
So what works 'fine', what 'gives error' and which code did you try? That code compiles OK here now. It just is too large so you need to adjust the sizing to fit it onto the sheet or use a larger piece of paper. — cfr, Mar 31 '14 at 03:03
@Harry Why don't you just change the direction so that before the end of the page, you switch the flowchart to the right or whatever? As in the image you posted? — cfr, Mar 31 '14 at 23:51
By the way, it's "optimality criterion", not "optimilalty cretierin". — LSpice, Aug 29 '21 at 15:10
