Optimal density of economic benefit

Module content

The best economic benefit density module mainly optimizes the planting density. After you upload the data file in the correct format, the system will calculate the optimal planting density range when the economic benefit yield is the largest. The operation results of the system will be displayed from three aspects

Data table display
This section shows the data you entered and the output data predicted after system modeling
Model operation and selection
This part not only shows the best model of system selection and the expression of economic benefit output model, but also shows the estimated value of model parameters and MSE of model fitting
Data visualization
This part shows the diagram of the best planting density range, the curve of the best yield density model and the goodness of fit test chart of the model

Module implementation method

1. Determine the economic benefit output model

Using genetic algorithm to fit the production cost function, and using module one method to determine the yield density model, the economic benefit yield model is obtained: economic benefit yield = crop yield production cost

2. Determine the intersection equation and solve it

Graphic method is used to determine the intersection equations of the optimum density and the range of optimum density

The dichotomy method is used to solve the above equation

3. Data visualization

The data visualization is realized, and the legend is shown as follows:
