1. Micro-Logistics Matrix (Traveling Salesperson Problem - TSP)
An interactive spatial router solving the NP-hard Traveling Salesperson Problem using a deterministic brute-force permutation algorithm for up to 9 nodes on a 2D coordinate plane. Computes optimal path matrices, travel cost metrics, fuel pricing vectors, mechanical wear and tear, and CO2 emissions profiles. Key equations: Total Distance = Σ d(v_i, v_{i+1}).
2. Shannon Information Entropy & Communication Limits
Computes the mathematical information bounds of text streams based on Claude Shannon's source coding theorems. Calculates frequency distributions, entropy (H) in bits, compression thresholds, Levenshtein edit distance, and compiles dynamic binary Huffman coding tree tables for optimal data structures. Formula: H(X) = - Σ P(x_i) log2 P(x_i).
3. Bio Genome Sequencing & Peptide Translators
Aligns nucleic sequences (DNA / RNA) to translate triplet codons into peptide chains according to the standard genetic code. Displays nucleotide frequency distribution ratios, translates sequences, and computes the Hamming Distance of mismatch pairs for evolutionary and bioinformatic distance models. Formula: D_H = Σ (s1_i ≠ s2_i).
4. Inventory Optimization & Economic Order Quantity (EOQ)
Calculates the optimal replenishment batch sizing for supply chain and manufacturing operations. Uses the Wilson-Harris formula to compute optimal economic order size (EOQ), safety stock levels (incorporating standard deviation of demand and lead times), total carrying holding vs setup ordering costs, and renders a live sawtooth inventory level depletion model. Formula: EOQ = √((2 * D * S) / H).
5. Spatial Center-of-Gravity (COG) Warehouse Locator
An industrial engineering coordinate locator calculating optimal centralized location indexes for distribution centers, manufacturing facilities, or shipping hubs. Computes weighted spatial moments on a Cartesian reference system using client volume weights (in freight tons) and locations. Formula: X_cog = Σ(X_i * W_i) / Σ W_i, Y_cog = Σ(Y_i * W_i) / Σ W_i.
6. Overland Travel Fuel, Toll & EV Battery Calculator
A multi-passenger trip transportation cost divider. Computes internal combustion engine (ICE) petrol/diesel costs, electric vehicle (EV) battery consumption rates in kilowatt-hours (kWh) per 100km, local highway toll splits, carbon dioxide offsets, and calculates passenger expense divisions across legendary routes (Route 66, Amalfi Coast, Ring Road, etc.).
7. Spacetime Relativity & Lorentz Transformations
Calculates the relativistic effects of Einstein's Special Relativity. Evaluates the Lorentz factor (γ), relative time dilation (t'), length contraction (L'), relativistic mass increase (m'), and corresponding momentum velocities in high-energy physics. Formulae: γ = 1 / √(1 - v²/c²), t' = t * γ, L' = L / γ, E = mc².
8. Kepler Planetary Elliptical Orbits Simulator
Simulates astronomical objects orbiting in Keplerian gravity wells. Solves Kepler's transcendental equation (M = E - e * sin E) using Newton-Raphson iterative root finding approximations. Computes semi-major axis lengths, true anomalies, orbital velocities, eccentricity limits, and animates equal orbital sweeps conforming to Kepler's Second Law of planetary motion.
9. Structural Loads & Beam Flexure Limits
A civil and mechanical structural load simulator designing beam deflection limits. Computes shear forces, bending moments, maximum elastic flexure stress, load displacement limits, and safety factor outcomes for Cantor and Simple Support types under Point or Uniformly Distributed Loads. Formula: σ = M * y / I.
10. Great Circle Geodesic & Rhumb Line Navigation
Computes extreme distance spherical navigational tracks across the Earth's surface using the Haversine and spherical trigonometry laws. Determines initial headings, orthodromic initial bearing angles, Rhumb line constant directions, antipodes, and calculates point-to-point geodesic gaps in kilometers and nautical miles.
11. Soroban Counting Frame (Japanese Abacus)
An interactive, high-fidelity virtual Japanese Soroban abacus. Promotes mechanical place-value mathematics, modeling integers, floating-point numbers, base-10 calculations, and standard arithmetic operations via sliding deck beads (5-unit upper deck, 1-unit lower deck).
12. TVM Compounding Forecast & Monte Carlo Simulators
Optimizes capital accumulation and compound interest dynamics under the Time Value of Money (TVM). Runs 100-path stochastic Monte Carlo simulations modeling dynamic inflation rates, volatility variables, real purchasing power curves, and confidence intervals (10th/50th/90th percentiles).
13. Black-Scholes-Merton European Option Pricing
Renders premium curves for European Style Call and Put options contracts using the Nobel-prize-winning Black-Scholes-Merton differential model. Computes first-order option sensitivities—Option Greeks (Delta, Gamma, Vega, Theta, Rho), implied volatility, and underlying asset price curves.
14. Forex Triangular Arbitrage Loop Explorer
Models currency pricing loop inefficiencies in three-way foreign exchange markets (e.g., USD -> EUR -> GBP -> USD). Evaluates bid/ask bid-spreads, transaction Commissions/slippages, and discovers positive-yield loops using real-world matrix paths.
