Multi-objective optimization for 3D heterogeneous WSN deployment using an enhanced Genghis Khan shark algorithm.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Heterogeneous three-dimensional (3D) wireless sensor network (WSN) deployment requires balancing sensing coverage, communication connectivity, and deployment cost under coupled K-coverage and C-connectivity constraints. This setting yields a constrained mixed discrete optimization landscape where many conventional multi-objective methods lose diversity or handle feasibility inconsistently. We formulate heterogeneous 3D WSN deployment as a constrained multi-objective problem and propose the Enhanced Multi-Objective Genghis Khan Shark Optimizer (EnMOGKSO). The core novelty is the integration of leader-pursuit dynamics with (i) dual archive-guided selection (elite and neighborhood memories), (ii) bounded external archive diversity control, and (iii) feasibility-first environmental selection for fragmented feasible regions. On the Congress on Evolutionary Computation (CEC) 2020 suite, EnMOGKSO obtains the best Friedman mean ranks in hypervolume (HV) (2.04) and inverted generational distance (IGD) (2.38), with statistically significant differences against most competitors ([Formula: see text], Wilcoxon/Friedman). In heterogeneous 3D WSN deployment, EnMOGKSO yields higher coverage/connectivity values (typically coverage means around 11-12 and connectivity around 7) than weaker baselines (often coverage 5-7 and connectivity 4-5), with higher but stable deployment cost. Overall, the results indicate a stronger convergence-diversity balance and more reliable feasibility-aware search under tight constraints, with practical applicability to 3D monitoring tasks such as industrial facilities, smart buildings, and environmental sensing.
