"complicated behavior" is correct and usable in written English.
You can use it when you are discussing something that has multiple behavior patterns or actions associated with it. For example, "John's complicated behavior was difficult to understand, as he often seemed to contradict himself."
Dr. Goldman initially studied the physics of granular materials, which display complicated behavior — changing from a solid to a fluid, for example.
They are key parts of a research program that is helping unlock one of biology's elusive secrets — how genes control complicated behavior.
The results illustrate complicated behavior of the ionosphere, also. 4.
Finally, Curtis McMullen of Harvard University was honored for his work in a variety of mathematical areas, including simple dynamical systems that can exhibit surprisingly complicated behavior.
There are significant theoretical researches on delay differential equation addressing many aspects of the dynamics, for example, stability of equilibria, existence of periodic solutions, complicated behavior, and chaos.
We believe that our family of piecewise linear difference equations are the prototypes for more elaborate piecewise difference equations that, in many cases as in the Lozi equation, exhibit complicated behavior.
Q. SO BIG BRAINS ARE NOT ALWAYS AN ADVANTAGE? A. Bigger is better if you want to produce enormously complicated behavior.
Dr. Hoekstra's work is unusual in that it deals with a naturally occurring, complicated behavior in mammals that is important for survival.
Specifically, the ridiculous is presented as completely ration, i.e. in the section on temperature description of at what degree adults function - males move twice as fast at 60 degrees, females show more complicated behavior which affects sexuality.
The architectural feats of animals — from beaver dams to birds' nests — not only make for great nature television, but, since the plans for such constructions seem largely inherited, they also offer an opportunity for scientists to tackle the profoundly difficult question of how genes control complicated behavior in animals and humans.
Robert Anholt, a specialist in behavior and genetics in fruit flies at North Carolina State University, said it was "courageous to undertake this particular work" for Dr. Hoekstra because of the great difficulty of dealing with complicated behavior, and that the approach was innovative and pushed forward what was possible in behavioral genetics.
