We return to the basic definition of distributed ealgebras in 6.2.
A pure sequential run  of an ealgebra A is a sequence
[ 
 :
n < 
 ]
 
of states of A, where 
 is an
initial state and every 
 is obtained from 
 by executing a
move of an agent.  The generalization to the case of external functions or
external locations is relatively straightforward.
