Yard crane is an important resource in container terminals. Efficient utilization of the yard crane significantly improves the productivity and the profitability of the container terminal. This paper presents a mixed integer programming model for the yard crane scheduling problem with non- interference constraint that is NPHARD in nature. In other words, one of the most important constraints in...

Student curiosity data measured a questionnaire instrument, while understanding solving abilities questi...

Mathematics is a basic science that has an important role. So, to achieve the objectives of learning mathematics, mathematical problem-solving abilities are needed. The ability students SMP PAB 3 Saintis at Deli Serdang still very low. It suspected Group Investigation and Rotation Trio Exchange models can improve students' abilities. purpose this research was determine effect taught using Excha...

Modeling general intelligence has a long history: At the beginnings of AI, researchers searched for the general problem solving mechanism to model intelligence. While researchers failed to solve this complex problem, AI achieved great success when modeling cognitive abilities separately. In recent time a growing number of research endeavors aims again at human–level intelligence via integrating...
