The paper is discussing an important issue about the discontinuity of urban pattern of Qasba city in Algeria. The research presented covers wide theories such as Space Syntax and demonstrated in-depth application of the theory on a practical case study. 
My main concern is with the number of missing references that were mentioned in the body of the paper and do not appear in the references section. There is also confusion in Figures 18 to 21 where I do not see the difference between the axial maps on the right and left side. This is a very important figure and the papers will be printed in black and white. Can the author show the difference by altering the line weights of these maps instead of using the coloring convention?
