WebAug 21, 2013 · Bacterial foraging optimization (BFO) is predominately used to find solutions for real-world problems. One of the major characteristics of BFO is the chemotactic movement of a virtual bacterium that models a trial solution of the problems. It is pointed out that the chemotaxis employed by classical BFO usually results in sustained oscillation, …

WebChemotactic factors are mediators that induce unidirectional leukocyte movement by establish- ing a concentration gradient of the chemotactic factor that increases toward an area of inflamma- tion. A number of different types of molecules can act as chemotactic factors (Table 1). WebChemotactic movement in response to local signals forms a streak through small local cell rearrangements, with little movement far from the streak (Fig. 1 and Fig. 7). To obtain large-scale flows requires some local mechanism that aligns the movement directions of neighboring cells, i., the tissue has to have viscous or plastic effective ...
