## Step 1: Define the optimization problem
The problem is to minimize the objective function: $3 \cdot (cherry \: pies)^2 + 6 \cdot cherry \: pies \cdot eggs + 4 \cdot cherry \: pies \cdot green \: beans + 1 \cdot (eggs)^2 + 3 \cdot eggs \cdot green \: beans + 9 \cdot (green \: beans)^2 + 5 \cdot cherry \: pies + 1 \cdot eggs + 8 \cdot green \: beans$

- $4 \cdot cherry \: pies + 10 \cdot eggs \geq 33$
- $4 \cdot cherry \: pies + 10 \cdot eggs + 4 \cdot green \: beans \geq 33$
- $10 \cdot (cherry \: pies)^2 - 1 \cdot (eggs)^2 \geq 0$
- $-1 \cdot eggs + 8 \cdot green \: beans \geq 0$
- $5 \cdot cherry \: pies + 6 \cdot eggs + 3 \cdot green \: beans \leq 41$
- $2 \cdot cherry \: pies + 7 \cdot eggs \leq 61$
- $8 \cdot eggs + 7 \cdot green \: beans \leq 111$
- $4 \cdot cherry \: pies + 7 \cdot green \: beans \leq 94$
- $4 \cdot cherry \: pies + 8 \cdot eggs \leq 49$
- $(1 \cdot eggs)^2 + (3 \cdot green \: beans)^2 \leq 30$
- $4 \cdot cherry \: pies + 10 \cdot eggs \leq 76$
- $4 \cdot cherry \: pies + 10 \cdot eggs + 4 \cdot green \: beans \leq 97$
- $cherry \: pies$ is an integer
- $eggs$ is a continuous variable
- $green \: beans$ is an integer
