Multi-Objective Self-Organizing Migrating Algorithm: Sensitivity on Controlling Parameters

In this paper, we investigate the sensitivity of a novel Multi-Objective Self-Organizing Migrating Algorithm (MOSOMA) on setting its control parameters. Usually, efficiency and accuracy of searching for a solution depends on the settings of a used stochastic algorithm, because multi-objective optimization problems are highly non-linear. In the paper, the sensitivity analysis is performed exploiting a large number of benchmark problems having different properties (the number of optimized parameters, the shape of a Pareto front, etc.). The quality of solutions revealed by MOSOMA is evaluated in terms of a generational distance, a spread and a hyper-volume error. Recommendations for proper settings of the algorithm are derived: These recommendations should help a user to set the algorithm for any multi-objective task without prior knowledge about the solved problem

A Novel Multi-Objective Self-Organizing Migrating Algorithm

In the paper, a novel stochastic Multi-Objective Self Organizing Migrating Algorithm (MOSOMA) is introduced. For the search of optima, MOSOMA employs a migration technique used in a single-objective Self Organizing Migrating Algorithm (SOMA). In order to obtain a uniform distribution of Pareto optimal solutions, a novel technique considering Euclidian distances among solutions is introduced. MOSOMA performance was tested on benchmark problems and selected electromagnetic structures. MOSOMA performance was compared with the performance of the Non-dominated Sorting Genetic Algorithm II (NSGA-II) and the Strength Pareto Evolutionary Algorithm 2 (SPEA2). MOSOMA excels in the uniform distribution of solutions and their completeness

Objective self-awareness theory: Recent progress and enduring problems.

Objective self-awareness theory has undergone fundamental changes in the 3 decades since Duval and Wicklund's (1972) original formulation. We review new evidence that bears on the basic tenets of the theory. Many of the assumptions of self-awareness theory require revision, particularly how expectancies influence approach and avoidance of self-standard discrepancies; the nature of standards, especially when they are changed; and the role of causal attribution in directing discrepancy reduction. However, several unresolved conceptual issues remain; future theoretical and empirical directions are discussed

A [email protected] Approach for Multi-objective Self-optimizing Software

This paper presents an approach to operate multi-objective self-optimizing software systems based on the [email protected] paradigm. In contrast to existing approaches, which are usually specific to a single or selected set of objectives (e.g., performance and/or reliability), the presented approach is generic in that it allows the software architect to model the relevant concerns of interest to self-optimization. At runtime, these models are interpreted and used to generate optimization problems. To evaluate the applicability of the approach, a scalability analysis is provided, showing the approach’s feasibility for at least two objectives

Nothing or the opposite: Intersecting terror management and objective self-awareness.

The human capacity for self-awareness allows people to envision their eventual death and thus creates the potential for debilitating anxiety. Terror management research has shown that self-awareness exacerbates the experience of mortality salience. I suggest that self-awareness alone can induce mortality salience through dialectical thinking. If constructs include a concept and its opposite, then focusing on one aspect should also increase awareness of the opposite. Focusing on the existing object self should thus lead to the recognition of the non-existent self that is implied. In Study 1, participants experienced one of two self-awareness manipulations (exposure to a mirror, perceiving the self as distinctive) or no manipulation; mortality salience was measured using a death-relevant word completion task. Both self-awareness conditions reported significantly higher mortality salience than the control condition. In Study 2, participants exposed to their reflection reported increased death-salience and life-salience (as measured by death- and life-relevant word completion tasks) than a control group, which directly suggests that self-awareness leads people to dialectically consider opposing facets of the self. Terror management and objective self-awareness theories might thus be more intimately tied than was previously thought

The effect of objective self-awareness on judgments of noncontingent act-outcome relations

Female college students\u27 perceptions of control over outcomes were examined in a high outcome, noncontingent, bivariate, act-outcome task. Logit regression revealed that the odds of judging low control and the odds of judging no relation increased when subjects performed the task in the presence of self-focusing stimuli. When subjects performed the task in front of a mirror, or in the presence of a video camera or an observer, the odds of judging low control increased by a factor of 2.57, 2.74, and 2.74 respectively. Subjects in the mirror, camera, and observer conditions also judged no relation between actions and outcomes with greater frequency; the odds of judging no relation in the mirror, camera, and observer condition increased by a factor of 1.78, 3.14, and 3.43, respectively. Measures of depression and individual differences in self-consciousness predicted neither low judgments of control nor judgments of no relation. Linear regression on measures of control judgment accuracy indicated that self-aware subjects also judged control accurately with respect to the objective contingency of act-outcome events. The results of this experiment demonstrate that self-aware subjects performing in a noncontingent judgment of control task are less susceptible to the illusion of control than those not self-aware

Noticing the self: Implicit assessment of self-focused attention using word recognition latencies

Self-focused attention is difficult to measure. Two studies developed an implicit measure of self-focus based on word recognition latencies. Self-focused attention activates self-content, so self-focused people should recognize self-relevant words more quickly. Study 1 measured individual-differences in self-focused attention. People scoring high in private self-consciousness recognized self-relevant words more quickly. Study 2 manipulated objective self-awareness with a writing task. People who wrote about distinctive self-aspects (high self-awareness) recognized self-relevant words more quickly compared to people who wrote about a neutral topic (low self-awareness) and people who did no writing (control). The discussion considers implications for future research on self-focused attention

The Self, Its Ideal, and God: The Implications of Non-Objective Self-Experience

This article explicates the unified argument of James G. Hart\u27s 1200 page work Who One Is. Hart begins with an exploration of the non-objective self as propertyless ipseity; then relates that sheer ipseity to the concrete development a self; and then, that self to the ideal self which guides its development; and finally, the ideal self to God as its origin. Hart also shows the relevance of Jaspers\u27 notion of Existenz at each of these stages. The uniqueness and “mineness” of any “I” cannot be a matter of properties. Each “I” is a unique “haecceity” for which multiple instantiation would be meaningless. Hart concludes with a fully developed theology of selfhood according to which God\u27s creation of the “haecceities” is an act of sheer generosity
