Some literatures investigated the odor source localization by robots mimicking biologic behaviors, such as chemotaxis [1] and anemotaxis [2], or custom algorithms like fluxotaxis [3] and infotaxis [4]. The multi-robot system has more advantages than single robot in odor source localization. First, the expected search time can be decreased. Second, the multi-robot system does not easily fall into local maxima.

My parents didn't want me to see him any more, but I finally won them round.

From the monistic standpoint there is a choice between two possible alternatives; either consciousness is a form of energy, like heat, etc., or it is merely a so-called epiphenomenon. […] It is essential to have a clear notion of what is meant by an epiphenomenon. […] It designates an accompanying incident of a process which is assumed to have no causal relation to the further development of the process. […] For many years I have tried to recognize some actual idea underneath the epiphenomenon hypothesis of consciousness, but it more and more seems clear to me that there is no idea at all, and that the hypothesis is an empty phrase, a subterfuge, which really amounts only to this—we can explain consciousness very easily by merely assuming that it does not require to be explained at all.

I feel that there is reason lurking in you somewhere, so we will patiently grope round for it.
