Optimizing the Layout of Proportional Symbol Maps: Polyhedra and Computation
, 2014
"... Proportional symbol maps are a cartographic tool to assist in the visualization and analysis of quantitativedata associated with specific locations, such as earthquake magnitudes, oil well production, and temperature at weather stations. As the name suggests, symbol sizes are proportional to the mag ..."

of computational experiments using hundreds of instances generated from real demographic and geophysical data sets. To the best of our knowledge, we are the first to use ILP to tackle this problem, and the first to provide provably optimal symbol maps for those data sets.
