conflicting, objectives. In this work, we contribute the multi-reward partially-observable Markov decision process
(MR-POMDP) as a general modelling framework. To solve MR-POMDPs, we present two hybrid (memetic) multi-objective
evolutionary algorithms that generate non-dominated sets of policies (in the form of stochastic finite state controllers).
Performance comparisons between the methods on multi-objective problems in robotics (with 2, 3 and 5 objectives),
web-advertising (with 3, 4 and 5 objectives) and infectious disease control (with 3 objectives), revealed that memetic
variants outperformed their original counterparts. We anticipate that the MR-POMDP along with multi-objective evolutionary
solvers will prove useful in a variety of theoretical and real-world applications.},

urban planning, public policies and infectious disease control. We contribute a complex weighted network
analysis of travel routes on the Singapore rail and bus transportation systems. We study the two networks
using both topological and dynamical analyses. Our results provide additional evidence that a dynamical
study adds to the information gained by traditional topological analysis, providing a richer view of complex
weighted networks. For example, while initial topological measures showed that the rail network is almost
fully connected, dynamical measures highlighted hub nodes that experience disproportionately large traffic.
The dynamical assortativity of the bus networks also differed from its topological counterpart. In addition,
inspection of the weighted eigenvector centralities highlighted a significant difference in traffic flows for
both networks during weekdays and weekends, suggesting the importance of adding a temporal perspective missing
from many previous studies.}}
