问题9：你能说说看，这个寻找素项的每 一步的理论基础吗？ EXAMPLE 15.8 Let E =xy+x'+xyz'+x'y'z+x'yz'.Then: E=xyz+x'z'+xyz'+x'y'z (x'yz'includes x'z) =xyz+x'y+xyz+x'y+xy (consensus of xyz and xyz') =x'z'+x'y'z+xy (xyz and xyz'include xy) =x'z'+x'y'z+xy+x'y (consensus of x'z'and x'yz) =x7+xy+x'y (x'y'z includes x'y) =x'z'+xy+x'y'+yz' (consensus of x'z'and xy) 显然，E有两个等价的素项表达，最终结果并不是极小式问题9：你能说说看，这个寻找素项的每 一步的理论基础吗？ 显然，E有两个等价的素项表达，最终结果并不是极小式
