Parameter Space Noise

Problem

Perturb parameters for exploration by adding sigma * noise elementwise. Return the perturbed parameter vector.

Hint

Parameter-space noise explores consistently across time, unlike independent action noise.

case 1

in: [[1,2],[0.5,-0.5],0.1]

expected: [1.05,1.95]

case 2

in: [[0],[1],0]

expected: [0]

case 3

in: [[1,1,1],[1,2,3],0.5]

expected: [1.5,2,2.5]
