ABSTRACT = {We consider an inverse problem for estimating an unknown time dependent heat source *H(t)* in a heat conduction equation *u*_{t}(x,t) = *u*_{xx}(x,t) + *H(t)*. First this inverse problem is formulated as a three-point boundary value problem (BVP) for ODEs discretized from the transformed homogeneous governing equation. To treat this three-point BVP we develop a two-stage Lie-group shooting method (TSLGSM). The novel approach is examined through numerical examples to convince that it is rather accurate and efficient; the estimation error is small even for identifying discontinuous and oscillatory heat sources under noise.},
