Hello everyone,
I’ve got some questions about the ‘difference factor’. In my unique
reference, Hiller and his colleagues proposed it for a system with three
spaces only.
*Hillier, Bill; Hanson, Julienne e H. Graham. ‘Ideas are in Things: An
Application of the Space Syntax Method to Discovering House Genotypes’.
Environment and Planning B: Planning and Design 14, 1987, pp 363-385*
This measure is based in the entropy, and its maximum value is ln(k) for
a system with k lines.
But, why doesn’t the minimum value is zero? Or, at last, a value
generated by the ‘linear graph’ – the maximum asymmetry ?
o ----- o ----- o ----- o ----- o
I’ve modified the formula to n spaces and tested it in some axial maps.
I’ve got results close to the maximum value for any map I’ve tested.
Anyone has ever used the difference factor for axial maps?
Thanks in advance,
