Task assignment problem (TAP) involves assigning a number of tasks to a number of processors in distributed computing systems and its objective is to minimize the sum of the total execution and communication costs, subject to all of the resource constraints. TAP is a combinatorial optimization problem and NP-complete. This paper proposes a hybrid meta-heuristic algorithm for solving TAP in a ...

In cognitive load theory, the superiority of Example-Problem sequence over Problem-Example has become a classic paradigm. The comparative effectiveness these sequences, however,...

objective: interventions for people suffering from borderline personality disorder (bpd), such as dialectical behavior therapy, often include a problem-solving component. however, there is an absence of published studies examining the problem-solving abilities of this client group in iran. the study compared inpatients and outpatients with bpd and a control group on problem-solving capabilities...

introduction: the term dynamic assessment (da) refers to an assessment, by an active teaching process, of a child's perception, learning, thinking, and problem solving. the process is aimed at modifying an individual's cognitive functioning and observing subsequent changes in learning and problem-solving patterns within the testing situation. da has been advocated as an alternative an...

Proper scheduling of tasks leads to optimum using of time and resources, in order to obtaining best result. One of the most important and complicated scheduling problems is open shop scheduling problem. There are n jobs in open shop scheduling problem which should be processed by m machines. Purpose of scheduling open shop problem is attaining to a suitable order of processing jobs by specified...

Activity management system deals with management and execution of activities. A problem solving agent is a human, or a hardware, or a software system having an ability to execute activities. An activity consists of multiple interdependent tasks that need to be coordinated , scheduled and executed by a set of problem solving agents, where each task is an atomic activity executed by exactly one p...
