UFLP: the series

There are currently 35 data files.

Format

All the values are integers. The format of these data files is:

number of users (nI)
number of services (nJ)
blank line    
costs for objective 1 c1(i,j) as a matrix with nI lines and nJ columns
blank line
costs for objective 2 c2(i,j) as a matrix with nI lines and nJ columns
blank line
costs for objective 1 r1(j) as a vector with nJ values
blank line
costs for objective 2 r2(j) as a vector with  nJ values

Instances:

The series F is has been created by Elena Fernandez. The collection has been generated in pasting two mono-objective UFLP.

• size : nI=90 and nJ=30
• correlation of objectives : near 0.0

The series H is has been created by Irina Harris and Christine Mumford. The collection comes from a green logistic project (objective 1 = costs; objective 2 = CO2).

• size : nI=2000 to 10000 and nJ=10
• correlation of objectives : near 0.99

The data files are:

• didactic1, didactic2
• F50-51, … , F56-57
• H10-2000, … , H10-10000
