  The behavior of the ensemble of coupled van der Pol oscillators is abundant
when coupling parameters are changed. Incoherent and chimera-like regimes are
observed at small values of the coupling strength parameter. Synchronization
takes place with an increase in the coupling strength and coupling range
parameters. Various chimera and solitary states are realised when the coupling
strength parameter is sufficiently large. The single van der Pol oscillator is
taken in the regime of relaxation oscillations. Therefore, the lattice may
realise spiral wave and spiral wave chimera regimes. Besides, target wave and
solitary state regimes are observed in the ensemble. Finally, the solitary
state and solitary state chimera regimes are firstly shown for the lattice of
coupled van der Pol oscillators.
