PROBLEM INSTANCES FOR
MULTI-INDEX ASSIGNMENT PROBLEMS
Each file corresponds to a
different multi-index assignment problem, axial or planar, as
denoted by its name. The number ‘K’ denotes the number of sets and the
number ‘N’ the cardinality of each set. For example, the file
“axial_K=5_N=12” corresponds to the 5-index axial assignment problem of order
12.
Each file contains randomly
generated objective function coefficients for 10 problem instances. Each
coefficient appears on a separate line, while each instance begins with a
heading denoting the values of K and N together with the instance number. For
example, “K=5, N=12, Problem 6” corresponds to the 5th instance of the 5-index
axial assignment problem of order 12. The coefficients are integer numbers
randomly drawn from the interval {1…N^K}. The coefficients are c_{m_1,
m_2,…,m_k} with index m_k varying fastest and index m_1 varying slowest.
