To find the right equation to solve the portfolio selection algorithm

I need to find the right expression to find the solution to the algorithm, being described in a paper titled "A simple Algorithm for Optimal Portfolio Selection with fixed transaction costs" by Nitin R Patel and Marti G Subrahmanyam.

Its hard to describe the problem without one reading the paper. IF you could google the title of the paper you would get it.

My issue is I am not able to understand how to Solve the objective function for the algorithm.....

please could someone tell me how they got those values in their example..!!??

Please give a direct link.
Or copy-paste what you want us to help you with.

I have been trying to attach the paper as an attachment but I am not able to do that!!
Is there any restriction attaching a file for a new member!??
