The Threshold

Demand Side:

If usage exceeds threshold:

→ Open more consumer-side conduits (routes, circuits, or batteries)

→ Spread load or delay usage (e.g., smart thermostats, EV charge throttling)

If usage drops:

→ Close unused paths

→ Reallocate power

Supply Side:

If generation exceeds threshold:

→ Route excess to storage, grid, or discretionary loads

→ Prevent overload and waste

If generation drops:

→ Prioritize critical demand

→ Close secondary paths

→ Possibly preemptively reduce lower-priority draw

How used:

Value added:

• Enables realistic simulation of diminishing impacts, efficient resource allocation, risk control, and improved system stability.

the general form of the recursive equation expressed only with letters (no symbols), in a word format:

f of x and n equalsif n is greater than maxDepth then return zeroelse return minimum of x and threshold plus f of (maximum of zero and x minus threshold multiplied by decay to the power n) and n plus one

Or more compactly as a sentence:

f(x, n) = if n > maxDepth then 0 else min(x, threshold) + f( max(0, x - threshold) × decayⁿ, n + 1 )

Power grid handles demand up to capacity; excess load shrinks and shifts recursively to backups. Simulation shows real-time input vs handled load to prevent overloads.

f(x, n) = if n > maxDepth then 0 else min(x, T) + f( max(0, x - T) * d^n, n + 1 )

Where:

x = input load

n = current layer

T = threshold capacity

d = decay factor

maxDepth = max backup layers

Absolutely! I'll break down the math representation of your recursive threshold-and-decay concept adapted to each of the 10 use cases. For clarity, I’ll use a general notation:

• xxx = input value (e.g., load, signal strength, demand)

• TTT = threshold

• ddd = decay factor, 0<d<10 < d < 10<d<1

• nnn = recursion depth or layer (starting from 0)

• f(x,n)f(x, n)f(x,n) = recursively processed value at depth nnn

The general recursive formula from your code:

f(x,n)={0,n>Nmax⁡min⁡(x,T)+f((x−T)+⋅dn,n+1),n≤Nmax⁡f(x, n) = \begin{cases} 0, & n > N_{\max} \\ \min(x, T) + f\big((x - T)^+ \cdot d^n, n + 1\big), & n \leq N_{\max} \end{cases}f(x,n)={0,min(x,T)+f((x−T)+⋅dn,n+1),​n>Nmax​n≤Nmax​​

• The recursive formula sums the capped threshold and recursively decayed excess, modeling diminishing impact across layers or steps.
