There are 270 data files.
  
The problem in each data file have an associated notation as follows:
  
 ins_10_100_30_03:	denotes that this is the 3rd instance
			in a group of problems
			with 10-dimensions, 100-items and
			the max 30%-uncertainty on profit intervals.

The format for each of these data files is:
  
 number of dimensions (m)	number of items (n)
 the minimum profit of item j (j=1,...,n)
 the maximum profit of item j (j=1,...,n)
 for each dimension i (i=1,...,m) in turn:
     resource consumed in selecting item j in dimension i (j=1,...,n)
 resource capacity of dimension i (i=1,...,m)
