Please find the code segment as below:
public int getNumberOfInstancesRequiredBasedOnMemoryConsumption(float
threshold, double predictedValue,
int
max, int min) {
double numberOfAdditionalInstancesRequired = 0;
if(predictedValue != threshold) {
float scalingRange = 100 - threshold;
int instanceRange = max - min;
* if(instanceRange != 0){*
float gradient = scalingRange / instanceRange;
numberOfAdditionalInstancesRequired = (predictedValue -
threshold) / gradient;
}
}
return (int) Math.ceil(min + numberOfAdditionalInstancesRequired);
}
