“…The deterministic model of Problem (1), i.e., when f (t) Ẇ is omitted, commonly known as the backward heat conduction problem (BHCP) has been extensively studied in the literature over the last few decades, see e.g. [2,3,4,5,9,12,13,15,16] to mention only a few. The BHCP arises in several practical areas such as heat transfer and image processing, [1,9].…”
