task graph scheduling is a multi-objective optimization and np-hard problem. in this paper a new algorithm on homogeneous multiprocessors systems is proposed. basically, scheduling algorithms are targeted to balance the two parameters of time and energy consumption. these two parameters are up to a certain limit in contrast with each other and improvement of one causes reduction in the other on...

In this paper we evaluate the effectiveness of agent-based aiding in support of a time-critical team-planning task for teams of both humans and heterogeneous software agents. The team task consists of human subjects playing the role of military commanders and cooperatively planning to move their respective units to a common rendezvous point, given time and resource constraints. The objective of...

According to an emerging view, decision-making, and motor planning are tightly entangled at the level of neural processing. Choice is influenced not only by the values associated with different options, but also biased by other factors. Here we test the hypothesis that preliminary action planning can induce choice biases gradually and independently of objective value when planning overlaps with...

This study investigates the combined effects of task-based careful online planning condition and the storyline structure of a task on L2 oral performance (complexity, accuracy, and fluency). 60 intermediate EFL learners were randomly assigned to four groups (n = 15). Participants were asked to perform two tasks with different degrees of storyline structure (structured and unstructured) under tw...

This study was aimed to compare long-term effects of collaborative and individual task planning on Persian-speaking EFL learners’ writing performance, using Brown and Bailey’s (1985) rating scale. Therefore, a group of 90 upper-intermediate EFL learners in collaborative task planning, individual task planning, and control groups took part in the study. In the experimental groups, the participan...

The current study aimed to examine the effects of strategic planning, online planning, strategic planning and online planning combined (joint planning), and no planning on the complexity, accuracy, and fluency of oral productions in two simple and complex narrative tasks. Eighty advanced EFL learners performed one simple narrative task and a complex narrative task with 20 minutes in between. Th...
