S. Cho, A. T. Murray, S. Dodge, and R. L. Church. 2025, Locational Decision-Making and Representational Impacts, The Professional Geographer

This research explored the disparity between the non-dominated solutions derived from continuous space and discretely approximated surfaces. The impact of spatial representation in spatial optimization was dealt in this paper.

S. Cho, S. Kim, and B. Lee. 2024, Correlation between Hotspots of Child Maltreatment and Neighborhood-Level Interventions, Child Indicators Research

This paper is dealing with the spatial pattern of child maltreatment and the impact of social and spatial context on it. The neighborhood intervention trend was explored in this research.

S. Cho, A. T. Murray, S. Dodge, and J. Baik. 2023, Improving Locational Decision Making: a heuristic that optimizes access and coverage, International Journal of Geographical Information Science

This research proposed λ interval heuristic method that can derive non-dominated solutions in continuous space. The results showed the superiority of the algorithm in continuous space to the derived solutions from the discretely approximated surface.

S. Cho and G. Lee. 2022, Spatio-temporal Multi-objective Optimization for Competitive Mobile Vendors Location and Routing Using De Facto Population Demands, Geographical Analysis

The optimal locations and trajectories of food trucks were identified considering the de facto population and existing restaurants in Seoul.
