鹰鸽博弈(Hawk-Dove Game),也被称为雪堆博弈,是一种演化策略模型,描述了两个物种在资源争夺中的互动。在Fortran代码中,为了模拟这个过程在一个四元组网格(N=4的方形格子)上,你需要编写一些涉及随机选择、竞争规则和更新策略的伪代码。以下是一个简化的示例:
```fortran
program HawkDoveSimulation
implicit none
integer :: N = 4, Iterations = 1000, Hawks(4), Doves(4)
real :: Energy(4)
! 初始化鸟的数量
do i = 1, N
if (random_number() < 0.5) then ! 鸿概率比鸽高
Hawks(i) = 1
Doves(i) = 0
else
Doves(i) = 1
Hawks(i) = 0
end if
end do
! 模拟过程
do iter = 1,Iterations
! 计算每个位置的能量(鹰获得优势,鸽则付出代价)
Energy = 0.8 * Doves - 0.2 * Hawks
! 更新策略:如果能量低,随机转化为对手
do i = 1, N
if (Energy(i) < 0) then
if (random_number() < 0.5) then
Hawks(i) = 1 - Hawks(i)
Doves(i) = 1 - Doves(i)
end if
end if
end do
end do
! 输出结果
print *, "After", Iterations, "iterations:"
do i = 1, N
print *, "Cell ", i, ":", "Hawk = ", Hawks(i), " Dove = ", Doves(i)
end do
end program HawkDoveSimulation
