Schema-Agnostic Process Trace Construction: From Raw Tables to Execution Behavior
Joel Lim Zhi Quan, Tan Kar Way, Lau Hoong Chuin
Traditional information systems (IS) engineering assumes stable schemas, explicit keys, and curated event logs. In modern OLTP environments, schemas drift, keys are sparse, and exe…
Probing Neural Combinatorial Optimization Models
Zhiqin Zhang, Yining Ma, Zhiguang Cao +1
Neural combinatorial optimization (NCO) has achieved remarkable performance, yet its learned model representations and decision rationale remain a black box. This impedes both acad…
A Nurse Staffing and Scheduling Problem with Bounded Flexibility and Demand Uncertainty
Si Zhang, Paul Mingzheng Tang, Hoong Chuin Lau
Nurse staffing and scheduling are persistent challenges in healthcare due to demand fluctuations and individual nurse preferences. This study introduces the concept of bounded flex…
A Comparative Study of Quantum Optimization Techniques for Solving Combinatorial Optimization Benchmark Problems
Monit Sharma, Hoong Chuin Lau
Quantum optimization holds promise for addressing classically intractable combinatorial problems, yet a standardized framework for benchmarking its performance, particularly in ter…
