For he seady-sae case and for given by h = Equaion () is he Eden-Fowler equaion [] [] [3] r = f ( ) and n f ( ) = and g( y) y y + y + af g ( y) = y ( ) = y y = (3) g y are soe given funcions of and y respecively. For = Equaion (3) is he sandard Lane-Eden equaion ha was used o odel he heral behavior of a spherical cloud of gas acing under he uual aracion of is olecules [] and subjec o he classical laws of herodynaics. For oher special fors of g( y ) he well-known Lane- Eden equaion was used o odel several phenoena in aheaical physics and asrophysics such as he heory of sellar srucure he heral behavior of a spherical cloud of gas isoheral gas spheres and heory of herionic currens [] [] [3]. A subsanial aoun of work has been done on his ype of probles for various srucures of g( y ) in []-[7]. On he oher hand he wave ype of equaions wih singular behavior is given by r ( ) r y + af g y + h = y < L < < T r> (4) or equivalenly r y + y + af( ) g( y) + h( ) = y < L < < T r> (5) will be eained as well f( ) g( y) + h( ) is a nonlinear source is he diensionless ie variable and y( ) is he displaceen of he wave a he posiion and a ie. The singulariy behavior ha occurs a he poin = is he ain difficuly in he analysis of Equaions () and (5). Wazwaz [8] used he Adoian decoposiion ehod (ADM) o ge an analyical soluion for he ie-dependen Eden-Fowler ype of equaions and wave-ype equaion wih singular behavior. The ain objecive of his paper is o apply Hooopy Analysis Mehod (HAM) o obain approiae-eac soluions for differen odels for he iedependen Eden-Fowler ype of equaions and wave-ype equaion wih singular behavior a =. While he VIM [9] [] requires he deerinaion of Lagrange uliplier in is copuaional algorih HAM is independen of any such requireens HAM handles linear and nonlinear ers in a siple and sraighforward anner wihou any addiional requireens. Also in his paper we apply Geneic Algorih (GA) o obain an approiae soluion of he sae equaions. In wha follows we give a brief review of Hooopy analysis ehod and Geneic algorih.. Analysis of he Hooopy Analysis Mehod To describe he basic ideas of he HAM we consider he following differenial 694
3 equaion: = N y k (6) N is a nonlinear operaor and denoe he independen variables y( ) is an unknown funcion and k( ) is a known analyic funcion. For sipliciy we ignore all boundary or iniial condiions which can be reaed in he siilar way. By eans of generalizing he radiional Hooopy ehod Liao [] consrucs he so called zero-order deforaion equaion ( q) L φ( q) y ( ) = qh N φ( q) k( ) ; ; q [ ] is an ebedding paraeer h is a nonzero auiliary paraeer L is an auiliary linear operaor y ( ) is an iniial guess of y( ) and φ ( q ; ) is an unknown funcion. I is iporan ha one has grea freedo o choose auiliary objecs such as h and L in HAM. Obviously when q = and q = i holds φ ; = y φ ; = y (8) respecively. Thus as q increases fro o he soluion ( q ; ) he iniial guess y ( ) o he soluion y( ). Epanding ( q ; ) Taylor series wih respec o q we have + = (7) φ varies fro φ in φ q ; = y + y q (9) y ( ) ( q ; ) =.! q q= () If he auiliary linear operaor he iniial guess he auiliary paraeer h and he auiliary funcion are so properly chosen he above series (9) converges a q = hen we have φ ( ) y ( ) y ( ) ; = + () which us be one of he soluions of he original nonlinear equaion as proved by Liao []. If h = Equaion (7) becoes + = ( q) L φ( q) y ( ) q N φ( q) k( ) ; + ; = which is used osly in he Hooopy perurbaion ehod []. According o Equaion () he governing equaion can be deduced fro he zero-order deforaion Equaion (7). We define he vecors { y( ) y( ) yi( ) } () y =. (3) i Differeniaing Equaion (7) ies wih respec o he ebedding paraeer q and hen seing q = and finally dividing he by! we have he socalled h-order deforaion equaion = L y χy hr y (4) 695

I should be ephasized ha y ( ) are governed by he linear Equaion (4) wih he linear boundary condiions ha coe fro he original proble which can be easily solved by sybolic copuaion sofwares such as Maple and Maheaica. 3. Geneic Algorihs Definiion Geneic Algorihs are search and opiizaion echniques based on Darwin s Principle of Naural Selecion. Definiion Geneic Algorih Operaors [3] [4] The siples for of geneic algorih involves hree ypes of operaors: selecion crossover and uaion. Selecion: This operaor selecs chroosoes in he populaion for reproducion. The fier he chroosoe he ore ies i is likely o be seleced o reproduce. Crossover: This operaor randoly chooses a locus and echanges he subsequences before and afer ha locus beween wo chroosoes o creae wo offspring. For eaple he srings and could be crossed over afer he hird locus in each o produce he wo offspring and. The crossover operaor roughly iics biological recobinaion beween wo single-chroosoe (haploid) organiss. Muaion: This operaor randoly flips soe of he bis in a chroosoe. For eaple he sring igh be uaed in is second posiion o yield. Muaion can occur a each bi posiion in a sring wih soe probabiliy usually very sall (e.g..). Algorih 3 A Siple Geneic Algorih [3] [4] Given a clearly defined proble o be solved and a bi sring represenaion for candidae soluions a siple GA works as follows:. Sar wih a randoly generaed populaion of n l-bi chroosoes (candidae soluions o a proble).. Calculae he finess f( ) of each chroosoe and in he populaion. 3. Repea he following seps unil n offspring have been creaed: (a) Selec a pair of paren chroosoes fro he curren populaion he probabiliy of selecion being an increasing funcion of finess. Selecion is done wih replaceen eaning ha he sae chroosoe can be seleced ore 696
5 han once o becoe a paren. (b) Wih probabiliy pc (he crossover probabiliy or crossover rae ) cross over he pair a randoly chosen poin (chosen wih unifor probabiliy) o for wo offspring. If no crossover akes place for wo offspring ha are eac copies of heir respecive parens. (Noe ha here he crossover rae is defined o be he probabiliy ha wo parens will crossover in a single poin. There are also uli-poin crossover versions of he GA in which he crossover rae for a pair of parens is he nuber of poins a which a crossover akes place). (c) Muae he wo offspring a each locus wih probabiliy p (he uaion probabiliy or uaion rae ) and place he resuling chroosoes in he new populaion. If n is odd one new populaion eber can be discarded a rando. 4. Replace he curren populaion wih he new populaion. 5. Go o sep. Also see he flow char (Figure ). 4. Applicaions of he Mehod In his work we eaine si disinc odels wih singular behavior a = wo linear ie-dependen Lane-Eden ype of equaions wo linear odels of wave-ype equaion and wo nonlinear singular odels.

Tweny poins have been used in he Sipson rule. The copuaions associaed wih he eaples were perfored using a Maple 3 package wih a precision of dgis. 4.. Tie-Dependen Lane-Eden Type Eaple.

Conclusions To our bes knowledge his is he firs resul on he applicaion of he HAM wih GA o solve odels of he ie-dependen Eden-Fowler ype of equaions and wave-ype equaion wih singular behaviors. The HAM wih GA has been successfully applied o solve odels of he ie-dependen Eden-Fowler ype of equaions and wave-ype equaion wih singular behaviors. The HAM wih GA has worked effecively o handle hese odels giving i a wider applicabiliy. The proposed schee of HAM has been applied direcly wihou any need for ransforaion forulae or resricive assupions. The soluion process of HAM is copaible wih hose ehods in he lieraure providing analyical approiaion such as ADM. The approach of HAM wih GA has been esed by eploying he ehod o obain approiae-eac soluions of si eaples. The resuls obained in all cases deonsrae he reliabiliy and he efficiency of his ehod.
