LORD: OPTIMUM DATA ACQUISITION 



sense, however, cognizance must be taken of 

 dimensionality i)roblems to avoid foundering 

 in details, many of which may be irrelevant. 

 Possible alternative procedures to decrease 

 the number of strategies to consider would be 

 to: 1) combine various contiguous time periods 

 into longer units and thus effectively decrease 

 ni and 2) reject those strategies that, based on 

 the value of Yq available, have a sufficiently 

 high a priori probability of being nonoptimal. 

 The combining of time periods would be par- 

 ticularly appropriate near the beginning and 

 end of the run when relatively few fish are 

 entering the fishery and the consequences of 

 nonoptional procedures are not so serious. 

 Also, the necessity to consider increased or de- 

 creased fishing areas can often be resolved prior 

 to the start of fishing by consideration of the 

 preseason information contained in Yq.
