I should like to ask Dr. Hirt the following questions: ' ' - 



1. What computer was used? 



2. What running-time did the examples require? 



3. What limit does computational feasibility place on the complexity of 

 problems which can be dealt with?

Dr. Hirt and the Los Alamos group certainly deserve congratulations for 

 their pioneering efforts in this field.
