📦 Installation

npm install ea-sbc-rating-calculator

🎯 Quick Start

const { SBCRatingCalculator } = require('ea-sbc-rating-calculator');

const calculator = new SBCRatingCalculator();

// Calculate team rating
const teamRating = calculator.calculateTeamRating([85, 87, 83, 86, 84, 88, 82, 85, 86, 84, 87]);
console.log('Team Rating:', teamRating); // 85

// Find optimal SBC solutions for large inventories
const result = calculator.findOptimalSolutions({
    targetRating: 83,
    availableRatings: yourLargeClubInventory, // 150+ cards
    priceByRating: { 82: 800, 83: 1000, 84: 2000 }
});

console.log(`Found ${result.solutionsFound} optimal solutions`);
console.log('Best solution:', result.solutions[0]);
// Output: 6x83 + 4x82 + 1x84 = 910 rating points (optimal)

🎮 Real SBC Example

// Your club inventory (150+ cards, 70% below 84 rating)
const myClub = [
    ...Array(50).fill(75), ...Array(30).fill(80), ...Array(25).fill(82),
    ...Array(20).fill(83), ...Array(15).fill(84), ...Array(10).fill(85)
];

// Find cheapest 83-rated squad
const solutions = calculator.findOptimalSolutions({
    targetRating: 83,
    availableRatings: myClub,
    priceByRating: { 
        75: 200, 80: 400, 82: 800, 83: 1000, 84: 2000, 85: 3000 
    },
    maxSolutions: 5
});

// Results sorted by rating efficiency (lowest rating points first)
solutions.solutions.forEach((solution, i) => {
    console.log(`Solution ${i+1}: ${solution.totalRatingPoints} points, ${solution.price} coins`);
    solution.squad.forEach(group => {
        console.log(`  ${group.count}x ${group.rating} rated players`);
    });
});

        // Use optimal combinations for speed
        return calculator.findOptimalSolutions({
            targetRating,
            availableRatings: clubCards,
            priceByRating: marketPrices
        });
    } else {
        // Use comprehensive search for smaller inventories
        return calculator.findSquadSolutions({
            targetRating,
            availableRatings: clubCards,
            priceByRating: marketPrices
