Comparison of simulated annealing and hill climbing in the course timetabling problem

  Course timetabling is a task that must be performed by all higher institutions. It is very difficult doing this manually and even classified as nondeterministic polynomial (NP) complete in five independent ways. Several methods (heuristics) are used to solve this problem including local search optimization methods like simulated annealing and hill climbing. This paper compares these methods used to solve the...

A deterministic model for HIV infection incorporating identification rate in a heterosexual population: Mathematical analysis

  In this research, we developed a model for investigating the spread of HIV infection, which can result in acquired immunodeficiency syndrome (AIDS), through vertical and horizontal transmissions and introduced the concept of identification program by considering identification rate in heterosexual population which was qualitatively and numerically analyzed. We obtained equilibrium points of the model at two...
