Abstract

Purpose

The purpose of this paper is to present a comparison between two well-known Lévy-based meta-heuristics called cuckoo search (CS) and flower pollination algorithm (FPA).

Design/methodology/approach

Both the algorithms (Lévy-based meta-heuristics called CS and Flower Pollination) are tested on selected benchmarks from CEC 2017. In addition, this study discussed all CS and FPA comparisons that were included implicitly in other works.

Findings

The experimental results show that CS is superior in global convergence to the optimal solution, while FPA outperforms CS in terms of time complexity.

Originality/value

This paper compares the working flow and significance of FPA and CS which seems to have many similarities in order to help the researchers deeply understand the differences between both algorithms. The experimental results are clearly shown to solve the global optimization problem.

Abstract

Purpose

The purpose of this paper is twofold: first, it seeks to voice the concerns of educated youth in Egypt as they describe their work options and preferences. Second, it seeks to highlight the gravity of the policy gap in addressing work informality, drawing on some of the international experience in this field.

Design/methodology/approach

Qualitative research in the form of in-depth interviews, desk-review of policies, and descriptive statistical analysis of a recent national survey of labour in Egypt.

Findings

A large proportion of educated youth work within the realm of informality and there is a clear policy gap in addressing this issue. Contrary to what would be expected, young people value access to social security and work stability. They face systemic hurdles related to access to such benefits. Because of the legacy of guaranteed government hiring of the educated in Egypt, young people express a great appreciation of work in the government, for virtually being the only employer offering job stability and social security in the labour market.

Research limitations/implications

This paper addresses a gap in the literature on youth employment in Egypt, where there is a dearth of research focusing on the lived experience of employment precariousness. The majority of studies in this field relies on statistics with little qualitative research voicing the views of this group.

Practical implications

Reforms are more urgent than timely to extend social security and other measures of social protection to workers within the informal economy.

Originality/value

The paper builds on primary data and provides insights about the way educated youth perceive their working conditions and options. The paper also provides a discussion of the social security system in Egypt, its coverage, and possible reform approaches.
