# Parameter values

* Birth rate and const of downregulation are defined below in order to fit some experim. data

```python
d = .13 # death rate
α = .3 # low equilibrium point at expression of the main pathway (high equilibrium is at one)
θ = .45 # threshold value for the expression of the main pathway
κ = 40 # robustness parameter
```

* Symbolic variables - the list insludes μ & μbar, because they will be varied later

```python
σ, φ0, φ, x, μ, μbar = symbols('sigma, phi0, phi, x, mu, mubar')
```

* Main functions

```python
A = 1-σ*(1-θ)
Eminus = (α*A-θ)**2/2
ΔE = A*(1-α)*((1+α)*A/2-θ)
ΔEf = lambdify(σ,ΔE)
```

* Birth rate and cost of downregulation

```python
b = (0.1*(exp(κ*(ΔEf(1)))+1)-0.14*(exp(κ*ΔEf(0))+1))/(exp(κ*ΔEf(1))-exp(κ*ΔEf(0))) # birth rate
χ = 1-(0.14*(exp(κ*ΔEf(0))+1)-b*exp(κ*ΔEf(0)))/b
b, χ
```

$$\left ( 0.140168330860362, \quad 0.325961223954473\right )$$

```python
c_relative = 0.05
c = c_relative*(b-d)/b+(1-c_relative)*χ/(exp(κ*ΔEf(0))+1) # cost of resistance
c
```

$$0.00476805892072291$$

* Hamiltonian *H* and a part of it ρ that includes the control variable σ

```python
h = b*(χ/(exp(κ*ΔE)+1)*(1-x)+c*x)
H = -φ0 + φ*(b*(χ/(exp(κ*ΔE)+1)-c)*x*(1-x)+μ*(1-x)/(exp(κ*ΔE)+1)-μbar*exp(-κ*Eminus)*x) + h
ρ = (φ*(b*χ*x+μ)+b*χ)/(exp(κ*ΔE)+1)*(1-x)-φ*μbar*exp(-κ*Eminus)*x
H, ρ

H0, ρ0
```
