The point-to-point delivery and connection problems: complexity and algorithms

open access: yesDiscrete Applied Mathematics, 1992
AbstractWe consider the computational complexity of point-to-point delivery problems. These problems involve shipping one item from each one of p sources to p destinations might be prematched to sources (the fixed destination case), or a source's item might go to any destination (the nonfixed destination case).
