Sorting solutions play a key role in using evolutionary algorithms (EAs) to solve many-objective optimization problems (MaOPs). Generally, different solution-sorting methods possess advantages dealing with distinct MaOPs. Focusing on this characteristic, article proposes general voting-mechanism-based ensemble framework (VMEF), where can be integrated and work cooperatively select promising more robust manner. In addition, strategy is designed calculate the contribution of each method then...

The coordination compound copper(II) acetylacetonate, [Cu(acac)2], exhibits remarkable elastic flexibility due to the reversible rotation of molecules when crystal is twisted or bent without loss its crystallinity. effects external stimuli, including heat and strain, have been intensively studied on this material, but mechanical response pressure has not yet reported. Using high-pressure single-crystal X-ray diffraction method, we show herringbone-type [Cu(acac)2] demonstrates structural...

Controllable strategies for the design of molecular ferroelectrics have been actively pursued in recent years due to their promising applications modern electronic devices. In this work, we present a spiro‐driven approach new class ferroelectrics. Using 2‐morpholinoethanol (MEO) as bidentate chelating ligand and SCN− anion bridging co‐ligand, obtained neutral chain‐like ferroelectric coordination polymer, [Cd(MEO)(SCN)2]. Interestingly, it undergoes both thermal‐induced phase transition,...

Materials with zero linear compressibility (ZLC) can counterintuitively keep its crystal size along a specific direction under hydrostatic high pressure, which makes ZLC materials novel promising functional for compression resistance. Herein, the first time, we propose modular "dumbbell"-like model material design, is confirmed by three representative MCN2 (M = Ca, Fe or Li2) consisting of different structural units. Density theory (DFT) calculations reveals that effect occurs alternatively...

A material with the "hidden" negative linear compressibility (NLC) will expand along a specific crystal direction upon uniformly compression to critical pressure; such materials are thought be promising candidates for non-linear actuators, switches and sensors. Herein, we use density functional theory (DFT) calculations uncover hidden NLC in V-shaped molecular crystal, bis(5-amino-1,2,4-triazol-3-yl)methane (BATZM). The indicate that is normally compressed over pressure range of 0-3 GPa...

Zero linear compressibility (ZLC) and zero thermal expansion (ZTE) are unique rare properties because of their excellent resistance to pressure temperature, respectively. Metamaterials possessing both ZLC ZTE will have promising application prospects. Herein, we conducted density functional theory studies on MC4O4 (M = Pb Ba), which "dumbbell"-like structures with property reported previously. The results show that the two compounds exhibit over studied range 0 10 GPa along c-axis, is also...

In many practical applications, dielectric electromagnetic (EM) windows are usually under large-angle incidence of EM waves rather than normal incidence. To guarantee operation devices inside, high transmission must be maintained large incident angles, especially for TE-polarized waves. this work, we propose a method achieving broadband angles by embedding meta-atoms within plates. end, long metallic wires and S-shaped structures embedded in the original plate, former which will dilute...

Decomposition‐based evolutionary multiobjective algorithms (MOEAs) divide a problem into several subproblems by using set of predefined uniformly distributed reference vectors and can achieve good overall performance especially in maintaining population diversity. However, they encounter huge difficulties addressing problems with irregular Pareto fronts (PFs) since many do not work during the searching process. To cope this problem, paper aims to improve an existing decomposition‐based...

In this study, we challenge the previously commonly used empirical rule of thumb to explain abnormal compressive behaviors observed in ZnM(CN)4 (M = Ni, Pd) compounds. Instead, propose critical angle criterion that allows for direct prediction various framework structures based on four structural models. According criterion, with a smaller or larger than will exhibit negative linear compressibility area (NLC/NAC). A systematic analysis reveals accords all previous reports. The application...
