### Question:
SquaredHingeLossTerm extends SquaredHyperplaneTerm { @Override public void minimize(float stepSize, float[] consensusValues) { float total = 0.0f; for (int i = 0; i < size; i++) { LocalVariable variable = variables[i]; variable.setValue(consensusValues[variable.getGlobalId()] - variable.getLagrange() / stepSize); total += coefficients[i] * variable.getValue(); } if (total <= constant) { return; } minWeightedSquaredHyperplane(stepSize, consensusValues); } SquaredHingeLossTerm(GroundRule groundRule, Hyperplane<LocalVariable> hyperplane); @Override float evaluate(); @Override float evaluate(float[] consensusValues); @Override void minimize(float stepSize, float[] consensusValues);  }### Answer:
