The committee would meet twice a year ( or more frequently if necessary ) , with the option of using a working group structure to examine selected issues in greater detail ; and The committee would be chaired by the Department of Finance . A simple approach , called PMP ( Paris Metro Pricing ) , is suggested for dealing with congestion in packet networks such as the Internet . Thus the situation is more or less analogous to conventional medical CT scanning , where even though one cannot hope to uniquely reconstruct a function , $ f ( x , y ) $ from its line integrals in a finite number of fixed directions ( even if the line integrals are noiseless ) the usual algoorithms are seen to work well , as demonstrated via simulations . These qualities , which also respond to the demands of teaching professional and other service courses , include commitments to excellence in teaching and service , a recognition of the importance of skills-based instruction , and a willingness to act as a generalist instead of a specialist . This problem is a special case of the maximum lateness problem , a problem known to be $ NP $ - hard even for very restrictive special cases and for which there are no known polynomial time $ O ( 1 ) $ approximation algorithms .
