Consider these two parameter settings:

Setting A: p$-$innovate $=.1\mathrm{.}01,p-$forget $=0,p-$copy$=0\mathrm{.}01,$

payoff$-$biased $=$ true

Setting B: p$-$innovate $=1\mathrm{.}0E-4($a$.$k$.$a $0\mathrm{.}0001),$ p$-$

forget $=0,p-$copy $=1,$ payoff$-$biased $=$ true

One of the settings causes technology to steadily

increase evenly across the grid with each square

behaving separately to each other, the other causes

technology to increase a step at a time with

innovations rapidly spreading out from a single point.

Which setting causes technologies to spread out from

a single point?
