Coevolution of spatial ultimatum game and link weight promotes fairness

作者：

Highlights：

• The coevolutionary mechanism is introduced to better reflect the real situation.

• The link weight represents the strength of the game interaction.

• The link weight is adjusted by comparing payoff with weighted average utility.

• The increase of link weight boundary control parameter facilitates fairness.

• The influence of link weight adjustment amplitude is not so significant.
