Abstract

Two linked data structures utilizing virtual backpointers, the virtual double-linked list (VDLL) and the B-tree with virtual backpointers (VBT), are described. Four experiments that provide example measurements of the capabilities (behavior under multiple error conditions) and performance (time overhead) of both local concurrent error detection and correction using sample VDLL and VBT instances are described. For these structures, double errors within a fixed-size checking window can be detected in constant time, and single errors detected during forward moves can be corrected in constant time
