Pseudocode 1

Input: A P system    from  TSEC  and an input multiset  
Initialization phase:   is the initial configuration of  
while    is a non-halting configuration  do
Selection phase: Input  ,Output  
Execution phase: Input  , Output  
end while
Output: Yes  if    has an accepting computation,  No  otherwise
