This paper employs two integration procedures to obtain soliton solutions to the perturbed Gerdjikov-Ivanov equation. They are G'/G(2)-expansion method and the sine-cosine method. Bright, dark and singular solitons are revealed along with a few of the combo-soliton solutions. The existence criteria of these solitons are also given.
