Metaheuristics are the most selected techniques to find optimal solution intelligently in many areas of scheduling, space allocation, decision making, pattern recognition, document clustering, control objectives, image processing, system and filter modeling, etc. These algorithms have promised better solutions in single and multi-objective optimization. Gravitational search algorithm (GSA) is one of the recent created metaheuristic search algorithms, which is inspired by the Newtonian laws of gravity and motion. GSA was first proposed by Rashedi et al. and in the short time it became popular among the scientific community and researchers resulting in a lot of variants of the basic algorithm with improved performance. This chapter book presents a detailed review of the basic concepts of G...

Moreover, it was an attempt to scrutinize whether there was any significant difference between incidental lexical and grammatical collocation learning. To this end, 36 Iranian EFL learners attending Sadra English Institute in Yasuj participated in the study. They were selected based on the result of quick placement test (QPT) as 28 out of 36 elementary EFL learners. A total of 28 learners were assigned into one experimental group (n=15) and one control group (n=13). The result of the pre-test and post-test analysis using One-Way ANCOVA and MANCOVA revealed the fact that there was statistically significant increase in collocation knowledge of the learners. In addition, participants performed significantly on grammatical post-test than lexical post-test after the treatment.

Of the 290 Persian EFL learners attending several language institutes, 165 were randomly selected based on Krejcie and Morgan's (1970) guidelines. For data collection, Felder and Silverman's (1988) index of learning styles, Oxford's (1990) strategy inventory for language learning, and Pintrich and Degroot's (1990) motivational learning strategies questionnaires were utilized, and the learners' language (English) performance was assessed by their course scores. The results of stepwise multiple regression revealed that learning strategies, learning styles, and motivational learning strategies had contributory roles in the English achievement of the learners. Among learning styles, processes, perception, and input styles; among learning strategies, cognitive, compensatory, and metacognitive strategies; and among motivational strategies, intrinsic goal-oriented and metacognitive motivational strategies predicted the learners' English achievements. Overall, the results provide implications for instructors and learners to improve second/foreign (L2) performance.

Stroke, heart attack, and dialysis patients experience physical and cognitive disorders. This study was carried out to compare personality types, everyday memory, and rumination among stroke, heart attack, and dialysis patients. Methods: In this descriptive study, which followed by a causal-comparative design, 90 stroke (30), heart attack (30), and dialysis (30) patients were selected in Zahedan, in 2017, using a convenience sampling method. Data were collected using NEO Personality Types Inventory (NEO-60), Sunderland Everyday Memory Scale, as well as the Ghorbani Rumination-Reflection Questionnaire and were analyzed step by step via SPSS23. Results: Results indicated that there were significant differences among the stroke, heart attack, and dialysis patients with regard to openness. However, no significant differences were found considering other personality types (P < 0.05). Moreover, mean scores on rumination and everyday memory of the stroke patients were greater than those of the dialysis and heart attack patients. Conclusions: As long as a person's cognitive system is involved with stressful events related to a trauma, his/her memory structure has a low performance, which decreases adherence and response to rehabilitation and affects the person's quality of life as well as improvement of his/her performance.
