tance would be decreased by the vessel cutting 

 corners of the subsquares. Calculations for the 126 

 stations on the Univac 1108 system used about 

 60K of core storage and required 2 min of Central 

 Processing Unit (CPU) time. 



East Delta 



Cruise 55 was used to test the program for the 

 East Delta area also. Of 1 16 stations sampled, 105 

 were included in the computation of an optimum 



one-way cruise track. The other 11 stations were 

 located in blocks 45, 46, 47, and 48. They were, 

 however, added to the end of the optimized listout, 

 plotted, and labeled on the cruise track plot. The 

 actual cruise track distance for the 105 stations 

 was 229 grid units (approximately 1,061 km) 

 (Figure 6). The optimized one-way path was calcu- 

 lated to be 216 grid units ( 1,000 km), an improve- 

 ment of 5.8'7f (Figure 7). Calculations for the 105 

 stations used 60K of core storage and required 66 s 

 of CPU time.
