Abstract

Purpose

The purpose of this paper is to propose an algorithm that combines the particle swarm optimization (PSO) with the biogeography-based optimization (BBO) algorithm.

Design/methodology/approach

The BBO and the PSO algorithms are jointly used in to order to combine the advantages of both algorithms. The efficiency of the proposed algorithm is tested using some selected standard benchmark functions. The performance of the proposed algorithm is compared with that of the differential evolutionary (DE), genetic algorithm (GA), PSO, BBO, blended BBO and hybrid BBO-DE algorithms.

Findings

Experimental results indicate that the proposed algorithm outperforms the BBO, PSO, DE, GA, and the blended BBO algorithms and has comparable performance to that of the hybrid BBO-DE algorithm. However, the proposed algorithm is simpler than the BBO-DE algorithm since the PSO does not have complex operations such as mutation and crossover used in the DE algorithm.

Originality/value

The proposed algorithm is a generic algorithm that can be used to efficiently solve optimization problems similar to that solved using other popular evolutionary algorithms but with better performance.

Abstract

Purpose

The paper provides some fundamental observations on leadership from an Islamic perspective and the Islamic revealed knowledge. The purpose of this paper is to measure the association between Islamic leadership and the most common western forms of leadership namely; transactional, transformational, authentic, and ethical leadership styles as well as its relationship on leader’s effectiveness and organizational innovation.

Design/methodology/approach

An empirical investigation was conducted using portrait value questionnaire recommended by Schwartz (1994b), confirmatory factor analysis (CFA) followed by structural equation modelling (SEM).

Findings

The results indicated that Islamic leadership is positively and significantly associated with perception of leader effectiveness and innovation outcomes. In addition the findings revealed that Islamic leadership is positively correlated with transformational, ethical, and authentic leadership as well and not with the transactional leadership style.

Practical implications

Among the practical implications of this research is that while a large body of leadership research has adopted a variation of leadership theories, our results suggest that we should seize to pay attention to the influential Islamic leadership.

Originality/value

The originality of this paper is that it extends scholarly understanding on Islamic perspectives of management which is a relatively new and growing area of interest for academics and practitioners, in terms of both theory and practice.
