The use of the most of deterministic approaches without a numerically implemented mathematical model of gas sensors can lead to an ineffective optimal design and poorly defined optimization criteria owing to the presence of errors in oversimplified mathematical description.
After the relaxation transformation, the problem of (11) is still a non-convex optimization problem owing to the presence of auxiliary variable τ.
However, if the number of optimization variables increases owing to a large number of valves or wells, the optimization problem becomes quite complex and difficult to be tackled using classical optimization methods.
The XL1, meanwhile, wrangles 20 kW from the electric motor, owing to optimization of its lithium-ion batteries and its Formula One-like monocell chassis' aerodynamics, translating to a claimed 261 m.p.g.
Continuous-flow microreactors are now routinely used in bench-scale synthesis[ 1] and optimization[ 2] applications, owing to their small reactant inventory, negligible heat effects at small scales, and fast mixing.[ 3] However, miniaturizing multiphase heterogeneous catalysis on chips is considerably more difficult than homogeneous liquid phase chemistry.
DEA has several advantages including (i) computational efficiency owing to its linear optimization structure; (ii) objectivity and consistency of results, which follows from not requiring the adjustment of parameters or assigning weights to the different performance measures; and (iii) capability of analyzing several microarray experiments with incommensurate units.
The genetic algorithm (GA) seems to be the best solution owing to its multi-objective optimization capability[12].
A planar heterojunction was again utilized, and with interlayer optimization, a PCE of 6.4% was achieved owing to a VOC of 1.03 V, a JSC of 9.0 mA/cm, and a FF of 71%.
However, ABC algorithm is criticized owing to its poor convergence rate and local optimization problems [3 6].
