Hi, Alan,
Do you think these agents are short sighted or geometry oriented? They
determine their move in a step by step fashion. In our agent-based
simulations, which were inspired by PageRank's random surfer model, the
agents are long sighted or topology oriented.

Just an idea out of the discussion. Your comments in particular.
Cheers.

The difference is explained by agents having forward facing vision and a process that leads to them moving towards open space. What IKEA designers had done was to ‘hide’ shortcuts by always hiding them behind partitions so that with forward facing vision you would have turn round to see the shortcut. Agents tend not to turn round but keep going forwards and do miss the shortcuts. This difference leads to a completely different analysis result. in VGA you can set the angle of vision number of bins to 32 - i.e. to 360 degrees and then the result approximated vga integration more closely.

So far I understand Axial & VGA analysis gives an understanding of configuration and in case of simulation, agents follow the clues of the morphology/configuration. In one case Agent simulation (any point) appears totally different from Axial/VGA (Integration) results. Agents prefer a route which can not be explained by any means. Why?
