multiple objective programming (mop) problems have become famous among many researchers due to more practical and realistic implementations. there have been a lot of methods proposed especially during the past four decades. in this paper, we develop a new algorithm based on a new approach to solve mop problems by starting from a utopian point (which is usually infeasible) and moving towards the...

Three dimensional user interfaces can help users in time-critical situations to improve their ability to solve problems. But they also may distract them from fulfilling their tasks with efficiency and effectiveness. This requests to control and limit the distraction caused by usage of those interfaces. Therefore it is necessary to measure and compare distraction caused by three dimensional user...

Abstract Single-objective continuous optimization can be challenging, especially when dealing with multimodal problems. This work sheds light on the effects that multi-objective may have in single-objective space. For this purpose, we examine inner mechanisms of recently developed sophisticated local search procedure SOMOGSA. method solves problems based first expanding problem an additional ob...

This essay offers an account of the truth conditions of sentences involving deontic modals like ‘ought’, designed to capture the difference between objective and subjective kinds of ‘ought’ This account resembles the classical semantics for deontic logic: according to this account, these truths conditions involve a function from the world of evaluation to a domain of worlds (equivalent to a so-...

In what follows I consider the apparent contrast between two kinds of theories of context: a theory of objective context-exempliied in the works of Kaplan and Lewis-and a theory of subjective context-exempliied in the works of McCarthy and Giunchiglia. I consider then some diiculties for the objective theory. I don't give any formalization; instead I give some theoretical points about the probl...
