where C c is current cycle number,, D is length of solution, F c is current best fitness.
To prepare an electrode for use, it was first back-filled using a disposable plastic Pasteur pipette (Phenix Research Products, Candler, NC, USA; cat # PP-137030) heat-pulled to a fine filament, with a 1 cm length of solution containing 100 mM of the ion to be measured.
We addressed this question both for the individual interventions implemented and for the lengths of solutions observed for the virtual patients.
To address solution lengths, we considered the lengths of "solutions:" sequences of interventions required to complete the solution (or non-solution) of an individual virtual patient in the mechanical ventilation data.
Figure 4 shows the influence of mutation rates on the length of evolved solutions for the shortest and longest evolutionary targets, respectively.
If the length of the solution vector D is large, it makes inefficiency improvement in each cycle.
The dependence of this relation on the Debye length of the solution and the initial fluid pressure in the membrane is also investigated.
The first one searches for the best damping factor which effectively determines the optimum direction of the solution vector in the multi-dimensional variable space, and the second search is conducted along that direction to find the optimum length of the solution vector.
(iii) Crossover process Two crossover processes are discussed below: Single-point crossover: For each pair of parent solutions, (PY_1=(py_{11},ldots2},py_{1m}y_{1m})) and (PY_2=(py_{21},ldots2},py_{2m}y_{2m})), selected for crossover, an integer position k is selected randomly in the range [1, m], for crossover operation, where m is the length of a solution.
(vii) A solution is admissible, if and only if (a) it respects (ii), i.e. for every source edge at least one corresponding candidate edge is used in it (but not necessarily for that respective source edge, see the case n = 0 in (iii)), and (b) the length of the solution does neither exceed 120% nor fall below 80% of the length of the source route matched by this respective solution.
