We define a probe to be a single action sequence computed greedily from a given state that either terminates in the goal or fails. We show that by designing these probes carefully using a number of existing and new polynomial techniques such as helpful actions, landmarks, and consistent subgoals, a single probe from the initial state can solve by itself 683 out of 980 problems from previous IPC...

Cerebellar abiotrophy, a premature degeneration of cerebellar neurons, has been described in most domestic animals. Affected animals typically present with progressive neurologic signs after a variable period of postnatal normalcy. This report describes the clinical, histopathologic, and immunohistochemical (IHC) findings of cerebellar abiotrophy in an alpaca. The alpaca developed intention tre...

A 9-month-old male llama (Lama glama) was presented because of a rapidly growing mass on the right side of the face. Radiographs revealed a marked expansion of the right caudal face region with bone lysis involving the maxilla and the nasal, lacrimal, zygomatic, and palatine bones. Cytologically, the mass consisted of atypical round to polygonal cells with round nuclei and basophilic cytoplasms...
